<blockquote>Next up let's look at Plague of Toads on the Witch Doctor . The Crimson Rune color makes all of your frogs on fire and then something a little more gameplay oriented, you've got mana reduction (Golden rune) so you can have a lot more frogs and then Alabaster rune will blind monsters which gives you some crowd control ability and Rank unknown as was shown at then we change the skill panelcompletely and make a toad blizzard (Indigo rune) then finally we wanted to have a giant toad (Obsidian rune) but what's he going to do? He's going to eat monsters and he digests them but he doesn't digest the loot.</blockquote>

* Crimson: Flaming toads for fire damage.* Obsidian: Large Frog, fairly large, eats enemies.* Alabaster: Blind monsters.* Indigo: Rain of Frogs, spell changes to instead rain frogs onto the enemies, seems to be single target.* Golden: Reduced cost.
