Dungeon Master Nexus Cheats and Hacks

Permanent spell effects

You can exploit a bug in the game to get permanent spell effects.
If you cast the same spell a lot of times (more than 50) in a short time, the effect becomes permanent. The easiest way to achieve this is:

1. Mana consumption is smaller when playing in ‘Easy’ mode (but this is not mandatory).
2. Use a champion with 200 or more mana, or have several champions cast the same spell. You may also prepare mana potions in advance to restore your mana and keep casting spells.
3. Equip the ‘Dragon Spit’ because it halves mana consumption.
4. Cast one of these spells:
   Spell shield: (Lo Ya Ir)
   Torch: (Lo Ful)
   Light: (Lo Oh Ir Ra)
   Fire shield: (Ful Bro Neta)
5. Use the ‘!’ symbol to cast the same spell repeatedly (more than about 50 times).
