How to unlock the Collector achievement in SWORD ART ONLINE: FATAL BULLET - Definitive Guide
Note that the list is a work in progress.
EDIT: To get the second level of a skill, 100 activations are required. And the third level, 200 activations. Depending on your console, you can simply use the skill and reload the map. Thanks to KROGAN WARLORDS for pointing this out.
You will need to purchase a total of 100 skills and/or gadgets. There are only 18 gadgets so the rest will be from skills. You will get some SP while ranking up but nowhere near enough to purchase the rest of the skills you need. You can get 20 SP and 40 SP from the Medal Trader. Use this to get the rest of the SP required.
For this achievement, it is important to rotate skills often to avoid a long grind later on. I'd suggest using all your money to get the gadgets first (rather than buying new weapons or whatever), and begin buying new skills with your SP as soon as possible. Equip a few Level 1 skills and use them until they hit 50% proficiency, which will unlock the Level 2 version for purchase. This counts as a new skill for the achievement once purchased. Don't bother using the Level 2 versions as you need to hit 100% to unlock Level 3. It's a total waste of time, at least achievement-wise.
To purchase skills, you will use SP (Skill Points) which are earned by increasing your bounty. There is a set amount of SP you can earn via this method however, so the remainder you will need to trade for with your combat medals. See "Trader" for more info on that process.
Note: Bear in mind, not every skill will have multiple levels. If you see "Healing Bullet 1" for instance, that shows you it will have another level, so you should use it to unlock the next level. If there is no number on a skill, just buy it and move on to something else.
