* [[Alabaster rune]]: The toads also blind enemies.

* [[Crimson rune]]: Flaming toads add fire damage to their attack.

* [[Indigo rune]]: Changes the skill to a rain of toads, which fall down on the targeted location.

* [[Obsidian rune]]: One huge frog that uses a sticky tongue to capture and consume monsters in one bite. It spits out the treasure and items. Can eat [[Champions]] (possibly only at higher/highest rune level?), but not [[bosses]] or (presumably) bigger enemies.
