The ingame tutorial isn't exactly clear on this one. When I use a skill, the little Interface showing Chain skills appears with a time limit. I know that when I use the skill within the time limit, I get the Phase 2 Bonus, right? But if I don't use the skill right away and let the time limit expire, I can still use the Phase 2 skill for some time, but do I get the Phase 2 Bonus then, or not?
Another thing, can you link different chains together? Let's say I have the skills A, B and C in the first quickslot, and then I have the skill C and D in the second. Now I press 1 to do skill A, again 1 to do skill B, but I press 2 instead of 1 to do skill C (within the time limit), will I still get the Phase 3 Bonus for Skill C, and start the new chain so I get the Phase 2 Bonus for Skill D?
