Not sure how, but Devouring deals damage properly

It's a mess, but all this code will be changed massively soon anyway.
Various changes and fixes

Introspection: Restore moved to 1st tier, Greater Insight to 2nd.
Tentacles: Requirements fixed.
Visionary Combat: Fixed activation time, fixed summoned tentacle tile.
Visionary Warrior: 2nd talent fixed, talent names changed (I hate them and they will be changed again)
Gauth starting runes: Manasurge changed to Phase Door (hey, it works)
