Yeah... This needs fixing for a number of reasons.
Like I mentioned, you can become a type of hybrid by dedicating spellslots or adapting your spirit to work with it (although the spirit armour has a huge weakness to blunt force) but just saying "So, yeah, hybrid." doesn't work. Being able to summon an immortal spirit (it's dispelled when it takes too much damage) is a very versatile tool, so giving the holder the same kind of power as a bishop, even with a spell or so less, is completely op. In fact the versitality of the knight is compromised by the vulnerability of the holder.
Besides, judging by your abilities, Eidren works just like a Bishop anyway
EDIT: 8+7+6=21 and I assume that by LEAP you mean JUMP?
Also light equipment and armour are a gigantic amount of spells. Specify them. Also add a CD to the active.
What's the radius increase to the holy beam?
What is the numerical value of the stat boost to active of the angel transformation?
