Ideas and suggestions.

At the level of slogans, the idea is clear. But I'm not suggesting removing the magic system from the game; I'm suggesting tweaking its oddities. (In terms of "numbers," change the number of overpowered spells in the schools of magic; in terms of atmosphere/imagery, resurrecting in water, in my opinion, looks even more atmospheric than in earth; in terms of damage, the fire spell needs an icon redesign (as does the resurrect spell), but in terms of imagery/atmosphere, fiery portals to other dimensions look normal).
As for the skills, either make them exactly the same as necromancy (adjust the numbers for logistics/offense/armor/jeremy), or make them one step better (give bonuses when leveling up the current "dead" skills that cannot be obtained in any other way).
