First i want to say that eertyek_the_mad's post had a bit to much so this is the more recent one post your ideas on here please .
ok so now onto the characters,
Caster
Cultist Moderate in everything except sanity,
Shadow ball:summons a ball of darkness doing some damage and with talents can chain into a smaller ball if the target dies and then hits up to another 3 enemys dealing 33-34 % of the damage of the shadow ball.
1-3 on talents #1 10-15 % of base damage #2 20-26 % of base damage and #3 33-34 % of base damage per ball.
second part of the extra talents: the shadow ball may pass through the enemy and instead of doing damage it goes to a teammate healing for 30 % of base damage and giving a double damage boost for 2-6 seconds.
second attack: Wave of Insanity whichever way the cultist is facing anything that stands in its way will go insane randomly attacking anything around it and it wont just affect enemys it will also effect TEAMMATES so be careful when you use it this effect lasts up to 6-8 seconds and the wave will go only a short distance so use it wisely!
extra talents: first talent gives a small chance that it wont effect your teammates 1-3 1 10 % chance 2 20 % and 3 30% chance it wont affect your teammates.
second talent gives your wave of insanity a small damage part in it so that way it will not only turn the enemys/your teammates insane but will also do some damage as well![this wont affect your teammates] 5-10 damage for the first upgrade in it 10-20 for the second and 20-35 for the third.
Third move, Mind control Mind control takes over the enemys mind and gives you control for up to 10 seconds! if you take damage this effect will end giving back the control of your character. first extra talent has a small chance that instead of mind controling kills the target and takes down half the health of a boss.
second extra talent: will go for a stronger target to mind control instead of any enemy and on the last upgrade you can take over a bosses mind as well! but only for 5 seconds instead of 10 since the boss is far stronger than any ordinary enemy i think that sounds reasonable.
Ok so since i just typed this whole thing for about half an hour im going to take a break now i will come back to it later ok thanks for posting!
