I need help with an Archdevil (PF/3.5)

[mostlyharmful]

- Racial HD, LA, etc. are not factored into overall character level.

- Level 30 Gestalt

- Base 18 in all stats before any moderators are applied

- Using Pathfinder with backwards compatibility.

- Characters have 1 billion starter gold (Artifacts cost 1-10 mill)

- Characters have 25 Divine Ranks

This isn't an Archfiend, this is an Overdeity. This is what Pun pun eventually turns himself into, are you sure that 3.5 DnD is the right game for this power level?
