Mana & Casting
What is mana?
Spells cost mana. The bar appears on the HUD after you learn your first spell.
Skills vs spells vs bar
| Idea | Meaning |
|---|---|
| Skill | Tree node you bought, e.g. Fireball rank 3 |
| Spell | Active ability the skill grants |
| Skill bar | 7 hotkey slots—you must equip spells here to cast with keys |
Flow: learn skill → equip spell → press hotkey → spend mana → cooldown
Keys: UI & Controls.
Mana costs (reference)
| Spell | Mana | Notes |
|---|---|---|
| Ignite | 5 | Empty-hand right-click, not on bar |
| Fireball 1/2/3 | 8 / 12 / 20 | Higher rank = more damage |
| Thunder Strike | 25 | Area true-damage lightning |
| Flame Dash | 20 | Dash + fire wall |
| Firestorm | 40–50 | By rank |
| Swift Surge | 15–25 | Short speed boost |
| Lightning Bolt 1/2/3 | 10 / 14 / 18 | Arc projectile strike |
| Summon Undead | 35 | Fixed cost |
Cooldowns from under a second to tens of seconds—wait for the icon.
Emerald Staff
Recipe: emerald + 2 sticks (shaped crafting).
- First right-click binds to you and permanently adds +20 max mana (once per character)
- Binding is stored on the item
- Useful for high-mana builds such as Summon Undead
Nothing happens?
| Situation | Fix |
|---|---|
| No response | Spell equipped? Right hotkey? |
| Not enough mana | Wait for regen or use mana potions if the pack has them |
| On cooldown | Watch the bar icon |
| No target | Thunder Strike needs hostiles nearby to lock |
| Ignite fails | Main hand must be empty; skill enabled in UI? |
| Summon Undead fails | Permanent summon cap reached; or rank 4+ without valid skull |
Tips
- Top off mana before fights
- Put frequent spells on R, T, etc.
- Firestorm and Swift Surge need positioning—don’t trap yourself
- Toggle Ignite off when mining to avoid accidents
