Curses would be very rare and often found on trickster’s staffs , which have a variety of 3-5 illusion and curse spells on them. Very rare and powerful, but difficult to find ( rarely found in dungeons, not very rare in end cities, rare in mineshafts, never found in desert temples, strongholds have usually at least one) but curses are only for players with high level magic, or finders of the tricksters staff. Illusion spells like mirror image, makes a temporary copy of either yourself or another mob, which is weak and has low health and attack damage, but fights with you until it dies, you can have up to 5 self copies or 8 copies of another mob at one given time, slow time, obviously slows time down in a 10 by 10 area for 2 minutes, slowing all movement including arrows, other spells, explosions, and other entities severely.confusion makes hostile mobs attack other random mobs other than the caster for 5 minutes and inverts a players controls, and causes nausea 3 for 2 minutes. Conceal makes a selected structure invisible to anyone except the caster until another player breaks a block of the concealed structure, or the caster casts conceal again. Cloaking makes the caster invisible for 5 minutes without the annoying potion swirls and armor becomes invisible as does an equipped staff or magic weapon.
And if anyone has other ideas or new spell suggestions, just suggest them , and hopefully this is made into a mod. To me, it seems like a good idea. And if there are any other ideas on how to obtain spells or crafting recepies for anything in the mod, I’m open for suggestions
