Steelrising

To unlock the Completionist achievement in Steelrising, you need to complete the entire game without using the Oil Burette — a recharging healing potion like the flasks in the Souls games. Healing via other methods is permitted, however, so you'll want to keep topped up with Ordinary Oil Vials, although bear in mind that these grant 20 seconds of slow health regeneration rather than an instant heal so you may still need to play cautiously when low on health.

While you can attempt this achievement on your first playthrough, I would suggest saving it for a second or later run when you are more familiar with the mechanics and enemies — you will need to do multiple playthroughs for the completion due to several other achievements anyway. While a little tricky early in the game when resources are low, this achievement is not as bad as it sounds once you get into the game and more healing options become available to you as your build starts to come online. You will also unlock 'Titan assassin' after defeating the first proper boss on this no-Burette playthrough, and I believe this may be the only way to get it as it did not pop for me when I beat a later boss without using the Burette after having used it earlier in the game.



A tutorial will pop up after the first enemy you defeat, telling you to heal using the Oil Burette and to equip it to your Quick Access Belt. Do neither. While the achievement description states that using it during the tutorial is fine, other similar achievements in the game can be a bit finicky and it's not worth risking the entire run at the very first enemy, so I would advise against healing here, just in case. The prompt to heal (if you took damage) will disappear upon leaving the area, so using the Burette is not required to progress the tutorial. Leaving the Burette off your quick item bar should also prevent any accidental use later on.

Ordinary Oil will be your main source of healing and is available in fairly generous (albeit finite) supply in the Vestal Boutique for 100 Essence a vial, as well as being a fairly common world find and drop from enemies. Several Modules also allow you to heal when performing other actions, such as landing critical hits or counterattacks. To make best use of these, you can opt for an Agility-focused build (starting as the Dancer for an instant Agility boost) and the Nemesis Claws — a weapon obtained in a chest early in the game that can both stagger enemies quickly to set up criticals and perform counters with well-timed presses of LT to deflect and punish incoming blows. Some such Modules will become available in the Boutique over the course of the game, and others can be found in chests or dropped by mini-bosses.

Some general tips to help the run go smoother:

• Avoid unnecessary combat to save wasting healing items, while scavenging as much as you can. Agility weapons can take a while to chip away at enemies and therefore make group combat more dangerous, especially early in the game before you really start to power up, but you will still be able to gain plenty of levels just by picking up and using/selling the many Essence bundles you will find strewn around.
• Save other consumables for mandatory fights like bosses and enemies who drop key items. Grenades are powerful, so can help get through those key fights more easily, while protection vials can be useful against the relevent elemental bosses.
• As well as investing in your key stat (likely Agility, if you want those extra Module heals), put points into Engineering. Not only does this give you a large flat Armor increase per level to improve survivability, it also enhances item drop rate to get you more Oils and other useful consumables.
• If you want even more items, you can equip armour pieces that increase Loot Multiplier. It's worth using some Armor-boosting gear early on, but this becomes less important as you start to invest in Engineering for greater Armor gains.
• Completing side quests rewards decent amounts of Essence, so taking the time to do these will give you more opportunities to level up even if you choose to run past quite a lot of combat encounters to avoid damage.
• You are invulnerable during the opening animation for chests and gates after holding Y for long enough — use this to your advantage if you want to avoid fighting powerful enemies that may be guarding them, or groups that are following you.
• Know when to cut your losses to save burning consumables. If you take lots of damage at the start of a boss fight or from an early enemy after a Vestal, just take a quick death — any dropped Essence will be in easy reach and your next run will hopefully get off to a better start.

Bonne chance, mes amis!
