DRAGON BALL XENOVERSE 2

The Hero Colosseum is quite the time and TP Medal dump, but if you know what you're looking for and use uploads, then you can shorten it heavily.

First off, you'll need TP Medals, so I hope you saved them from the main game and didn't use too many. I've found going back to the game after a long period will result in me having a large number of TP Medals to collect so if the same for you then good, that will be a nice boost.

Each wish on the Dragon Balls will grant you 200 TP if you choose that as what you want. Expert Missions can also be farmed if you wish it to be less random than the Dragon Ball farming. Failing that, you could always buy TP Medals off the shop to save you time.

Next, you'll need to make use of uploading your save file to Cloud Storage/USB to make sure you get what you want. The method is as follows, though free to modify it as you like. 30 spins of 20TP will give you a free spin for a UR. You can use the x5 20TP to speed it up, which is nice. Use the x5 20TP option 6 times and then use up the free UR spin. All in all it'll cost you 600TP Medals. You're looking for SSGSS Vegeta, Teen Gohan, and Whis, who are URs.

You'll need to level break some figures, so always make sure you dissemble the max amount of figures possible (20) each time; the rarity of the figures dismantled is irrelevant. Dissembling the max amount will result in more bonus figure experience and also give you the best level breaking chips which you need for the figures you're going to use to clear this. Make sure to not break down any speed type R Jacos you get, as you can combine them into your R Jaco for a stat boost to his speed. Same with SR Gohan and the URs of SSGSS Vegeta, Teen Gohan, and Whis.

Below is what I used. It is not the only way to clear it of course, and future updates may well introduce very broken figures/character skills that make this easier.

Figures

1: UR SSGSS Vegeta. The one with the effect that allows him to attack the opponent directly. Careful though as there are two versions, one with around 4500 attack and another with like 2500. You want the 4500 attack one. UR SSGSS Vegeta is very much key to clearing all the battles and his stats are pretty good anyway, able to withstand an enemy attack if it ain't from a heavy hitter (Broly for example who hits for like 10,000). Get him to level 99.

2: UR Teen Gohan. The version with crazy high attack and low health. While Vegeta can do all the work on many of the guys, later opponents will require you to bring in Teen Gohan to launch a massive Super Kamehameha. His health actually improves quite a bit though I put some defense boosting skills on him to allow him to better survive the 1 hit (he won't survive two). Get him to level 99.

3: UR Whis. The high health one. He is tanky and can take a hit and even better he makes your Teen Gohan/Vegeta more able to take that hit you'll need them to take. Level 40 did the job for me but feel free to level him beyond that if you wish.

4: SR Gohan. I actually had the type with lower health and didn't even level him up as he is there simply to give his posing skill (30+) to your ultimate gauge (him getting killed will further boost it). While playing, I noticed at times he'd survive as say a high speed low attack enemy would hit him and it would benefit me, while other times him dying would benefit me. Got by with him at lv1 but you might well want him to tank a hit - in retrospect, it likely would have been easier if he could tank a hit at a good rate.

5: R Jaco. The one with high speed. Note that N Hercule and N Jaco (speed types) are basically the same speed; however, the R Jaco being a rare gets an extra character skill slot, which is big. Being a rare you can likely make good use of the combining feature to level a stat of his up. I didn't do it myself, but I guess speed would be the obvious just in case as when you deploy him you really want to go first. He is way too weak to survive against the later opponents, so boosting HP or defense is worthless, as is attack. Level him up to 50, which is his max.

Character Skills

Character skills are key. In earlier fights you can get by with Vegeta having the x2 attack if alone skill as you can take two enemy hits fine... however the later fights have guys like Broly throwing out 10,000 damage so... yeah... that eventually becomes impossible to use. You want to load Vegeta up with +10% damage dealt, +500 attack if in the front row, +20% damage if going second.

Teen Gohan wants +20% Ultimate Attack Damage as he'll be who will be using them (I've had him wipe out the whole field of even those overpowered Lv99 guys the AI has). For the other two slots, I actually had defense boosters. +700 defense if master is at below 50% and +700 if going second. Him taking a hit and surviving was often key in winning.

The rest aren't hugely important, but use whatever you want. +1000 speed if master at below 50% HP is a good one for R Jaco. +2% ultimate gauge if master goes below 50% is also sometimes a little boost that gets you there, ready for the ultimate a turn sooner. The - enemy team speed/defense if master goes below 50% are good options to take (your figures don't need to be on the field to activate character skills, they simply need to be alive).

Stuff to watch out for

In the later fights especially, an additional attack triggering for SSGSS is very much important. You often don't need both triggering, but in the later fights it really helps.

As Teen Gohan's ultimate attack damage boost activates when you go below 50% health you actually want to be reduced below 50% before you bring him in to first tank a hit and then later launch the ultimate attack. SSGSS Vegeta you want to tank a hit, and then bring him in again when Gohan is launching his ultimate. Whis is there to help Gohan or Vegeta, whoever you got that needs to survive that turn, survive. SR Gohan is there to boost ultimate. R Jaco is there for when Teen Gohan needs to launch his ultimate and you need to go first.

There are some enemies to watch out for also. Frost has a power that halves your attack and defense if he hits you first, so he gets put into your Vegeta Column and would weaken your direct attack, retry.

The UR Piccolo that reduces damage to the master by 50% is a killer too. UR Trunks who reduces it by 30% is less so, you can win even with it but still, nasty.

One of the later opponents, Beerus, has a Goku who when using his posing skill basically bars you from getting an ultimate as he reduces it by 15% at the end of the turn. So retry if it looks like he is going to deny you (you can survive if he is placed in a posing spot turn 1, but if during turn 2 then it's a bust).

The Janemba one or two of the final fights has is also like that Goku, so treat him the same.

Finally, there is the Zamasu in the final fight who along himself also heals the master by 30% (master has 30,000 health so that is 9,000 healing). I'd actually advise focusing fire down the middle (where he is likely to be) with two people (Teen Gohan with Vegeta behind him are what I used). Didn't kill him and he healed once but later Teen Gohan's ultimate disposed of him (and two others).

Misc

Spirit Bombs, as worthless as they are the majority of the time, can really help if you get one off as they take a third off everybody (including enemy master). They only activate if you are close to losing, and can activate as early as turn 3.

I cleared everything at Master LV35 so you don't need to grind all the way to the max or anything, but around that level is good. Had some fights where I tanked 2 direct attacks with really low health where I would have died if at lower health. I did for the record grind a few levels as doing the story missions and free battles won't naturally get you to LV35, but it was minimal (hour/2 hours). Vados in free battle would be the best person to grind against as you can beat her quickly without much risk of losing (use Vegeta with x2 if alone, attack directly, tank 2 direct hits, then turn 2 use Vegeta again but with two others with him to block possible direct hits/go first).

When dismantling, make sure to dismantle the full 20 (rarity irrelevant) so you can get a random T chip x10. If you have a particular type you need, then simply get 20 figures, upload your file to cloud/USB, and then dismantle them all and see what you get. If you get something you don't want then download the file and try again.

Keep in mind that even with all that above, it will still require retrying if the enemy places figures in bad places for you, retrying if Vegeta doesn't do an additional attack (not always required so don't retry every time if it doesn't happen turn 1). One of his two attacks having a follow up + Teen Gohan Ultimate is usually enough.
