Rockslide Spell
Feat 10
Source Pathfinder Rage of Elements
Prerequisites Elementalist Dedication, earth is in your elemental philosophy
You enhance your spell with elemental earth, causing chunks of stone to litter the ground. If the next action you use is to Cast a non-cantrip Spell that affects an area, a number of 5-foot squares in the area equal to the spell rank become difficult terrain for 1 round. These squares must be on the ground, and the entire area of difficult terrain must be contiguous. The spell gains the earth trait.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
ArchetypeThis feat belongs to an archetype.
EarthEffects with the earth trait either manipulate or conjure earth. Those that manipulate earth have no effect in an area without earth. Creatures with this trait consist primarily of earth or have a connection to magical earth.
SpellshapeSpellshape actions tweak the properties of your spells. You must use a spellshape action directly before casting the spell you want to alter. If you use any action (including free actions and reactions) other than casting a spell directly after, you waste the benefits of the spellshape action. The benefit is also lost if your turn ends before you cast the spell. Any additional effects added by a spellshape action are part of the spell's effect, not of the spellshape action itself.
