Lava
From Triangle Wizard Wiki
Lava contains mainly molten stone and can generally be found in volcanic areas, and of course the lower levels of Castle Everdoom. Lava is quite dangerous and only creatures who can fly or have the firewalk ability may pass over it safely. If you don't possess these abilities you will be slowed severely and take fire damage until you can climb out again.
Creature who have at least 95% resistance to fire can pass over lava without any trouble.
[edit] Tips
- A Dungeon Master may create lava using the Flood spell.
- Having Fire Halo active will grant you the firewalk ability.
