Use a Wizard to add elemental attacks and control to the party, but decide what the next spell must accomplish before spending mana. Damage and movement control solve different problems.
Choose the effect you need
The current player guide describes fire, ice and lightning options. Inspect the actual spell’s target pattern, cost and control description. A spell that prevents movement is not necessarily a spell that stops an enemy from attacking.
The original player guide uses inconsistent control labels in its class and combat sections. Read the installed spell and resulting status rather than assuming that a magical lock makes it safe to remain in melee range.
A sensible casting decision
- Check mana and the enemy’s visible condition.
- Decide whether the party needs immediate damage, fewer incoming actions or a chance to reposition.
- Read the chosen spell’s target and effect rather than relying only on its name.
- Keep enough recovery or backup capacity for a fight that lasts another round.
- Recheck the field after the enemies respond; control can end or fail to solve the immediate threat.
Do not assume the same element is always correct. This page does not reproduce an unverified resistance chart for every enemy.
When mana is low
The developer announced long reach for staves. If your equipped staff and current tooltip support that behavior, it can provide a weapon option from behind the front line. Check actual reach before relying on the action; not every object held by a caster has the same rules.
Avoid a rigid spell rotation
A large group, a single armored target and a low-health emergency call for different actions. Exact spell rankings, guaranteed freezes and maximum-damage combinations would need controlled tests. This page instead helps you choose among the options visible in your installed build.
Sources & version notes
The player guide’s class and general combat sections disagree on control terminology. No specific Arcane Lock status is adopted here; use the installed tooltip. Developer sources independently support elemental control and staff reach, not exact skill values.
