I want to expand on this and amend the Phoenix summon to:
Rebirth Flame: AOE fire+light damage that casts Raise III on party members and leaves behind a GEO-type luopan that gives Regen/refresh/regain to all within AOE. All trust magic summons are consumed/dispelled upon use.
Or that is consumes trusts summons to cast O_o. No probably no, just thought it sounded cool, like there's a Phoenix burden or something. But maybe that's the way: Liek how tusts have more power the fewer there are in a PT, maybe this works like the more trusts summons you sacrifice the better the phoenix summon is:
1 trust: only AOE regen;
2 trusts: AOE regen, and refresh;
3 trusts: AOE regen, refresh, and regain;
4 trusts AOE regen, refresh, regain, and AOE fire + light dmg;
5 trusts: AOE regen, refresh, regain, fire + light dmg, and raise gets cast on all within the AOE and the caster gets RR effect and HP/MP retored.
