User blog comment:Vitios/Yagdra, the Ash Worm/@comment-7814894-20130404204716

Instead of a worm, maybe try a burrowing centipede. Have his Innate passive give Fury based on the distance traveled underground, and maybe a magic damage modifer based on Ability Power and Level for his next basic attack when surfacing. His E will then be a toggle, with the 1 second delay on burrowing and surfacing. While burrowing, he maintains normal movement control, with possibly a movement speed buff, but can't move through structures and can't use Fireball, Blinding Ash, or basic attacks. He can still be targeted by spells and basic attacks, but gains a percent scaling damage reduction. Then have his R give the Lava trail with the slow and magic damage burn, remove the surfacing and burrowing delay, make him immune to crowd control, let him move through objects, and still give the passive Fury, but the distance required to recieve the Fury increases every time he recieves the Fury. This means it is still useful for escaping as well as for chasing, since the more he moves the longer it lasts, and there is no delay for surfacing/burrowing with a movement speed buff. Also, if he is under walls or structures when the ability ends, he takes Percent Total Health damage every second until he is no longer under obstacles. That way, he doesn't just glitch or die if under terrain. And just one more thought: since Blinding Ash has less range than his basic attacks, increase the Fury cost to 20 or 30 so it is more suited for initiating instead of fleeing.
