Design changes for Spells
- Original Spell Lists: Druid
- One thing to note, is that all spells that I am adding into this blog have the Spell list removed from them, besides anything I might be doing to tweak them for my home campaign. There is a source there if you want to look up the original version of the spell for your own campaigns, but mine does not need that information.
- What has been added is the Secret Crafts, which replace the spell lists, as all spells not from the players handbook will only be available as part of the secret crafts of the world.
3rd Edition Version
- Erode
- Transmutation [Air]
- Level: Drd 4
- Components: V, S, F/DF
- Casting Time: 1 action
- Range: Medium (100 ft + 10 ft /level)
- Target: All objects in a 60 ft radius area or one object.
- Duration: 1 round/level (D)
- Saving Throw: Fortitude half (D)
- Spell Resistance: Yes
You concentrate centuries of wind into a few continual gusts to erode away rock and stone. An area with a radius of 60 ft is enveloped in strong and steady wind, and every object made of rock or stone suffers 1d8 points of damage per round of exposition, bypassing their hardness. Objects get a saving throw only if they are being held or carried, and they use their owner’s save bonus. As an option, you can concentrate all the eroding wind on a single object, inflicting 4d8 points of damage per round. Creatures made or rock or stone like earth elementals and stone golems suffer double damage, including characters under the effects of elemental shape, flesh to stone, statue and stoneshin.
Focus: An hourglass.
