Spell efficacy

Spell Efficacy is a set of systems that alter the amount of mana available in an area due to environmental influences. There are several forms that this mechanic takes, and only certain categories of spells are affected.

Elemental Efficacy

When casting all Warrior Mage spells or Bard spells from the Elemental Invocations spellbook a number of environmental conditions, available to view via PERCEIVE/CONCENTRATE ELEMENTS, will be checked to determine how favorable the conditions are to that particular element, which will in turn control how efficiently your mana is used. You can think of this as having somewhat different levels of room mana available to you depending on the spellbook you’re using, though the under the hood mechanics are rather different than that description. This does not currently apply to mana supplied from cambrinth or HARNESS.

It depends on the overall climate, the season, the time of day and severity of weather.

Hybrid elemental spells

Most Warrior Mage spells and spells in the Elemental Invocation spellbook are fairly straightforward in their type, however, the following spells are hybrids and affected by conditions that affect both elements:

• Desert's Maelstrom - This is an Earth and Air hybrid.
• Shockwave - This is an Air and either Water or Fire hybrid depending on whether the metaspell is active or not.
• Breath of Storms - This is normally Electrical but when Will of Winter is in place it will use Water.
• Phoenix's Pyre - This uses Fire and will use Water in addition when Will of Winter is in place.

Environmental Efficacy

When casting ranger spells, the wilderness conditions will determine how efficiently your mana is used. You can think of this as having somewhat different levels of room mana available to you depending on the environment. This does not currently apply to mana supplied from cambrinth or HARNESS. (This replaces the old terrain modifiers that Ranger magic was subject to.)

This can be checked by using PACE.

Devotion

A Cleric's devotion level affects how much mana they have available. With higher devotion they will effectively have more mana available to cast their spells with.
