After a while i feel i can contribute a few more ideas since my barren spell
1.This idea is both a graphical one and a skill. I fel that when you kill an enemy(a human) its corpse should be still whole if i can put it that way. After a period of time that corpse may deterioate to a half flesh/half skeleton and ater another peroid of time...the corpse would be just a skeleton.
Now with this skill called soul trapping when you kill the human being and cast the spell the human becomes a zombie and at first is friendly but when you leave and the come back again it becomes hostile and attacks.
The second level of the skill allows you to wiat until the corpse becomes half flesh and half skeleton and then cast the spell which then becomes a dark zombie.
Third level....If you wait for the corpse to become a skeleton then it becomes a skeleton lord.
Fourth level...You gain two creatures instead of one and the fifth level allows you to actually trap not the original soul but that of a powerful demon which which be around level 45.
2. Second idea is what i call satisfaction. You choose a weakness for your hero whereby doing ths particular action causes the hero to remain content. E.g the choices could be... Food,gems,drink or gambling.
I.e say every few days or so you hero has to either eat buy gems,gamble,stuff himself,get drunk.. etc depending on what you choose and if you dont then your hero will be sloppy,slow and have his attack rating decrease by some.
3.Now when you kill a monster(not human) this has the effect of attracting other monsters(not leaders) to the corpse say 1 day ater you ,kill it the chance is around 10%.The monster would depend on the level.
