Here's my proposal:
Bubonicus (Reference: http://www.wowwiki.com/Abomination)
- Innate - Slow Poison
Passive. Standard slow poison.- Innate - Gather Corpse
Auto-castable. Gathers a nearby corpse and stores it within Bubonicus's body.
Bubonicus can store 3 corpses at one time.
The Gold Mound can produce 5 corpses at a time, and will produce one every 60 seconds.
While Bubonicus has a corpse inside of him, he leaves a lingering disease cloud where-ever he goes that deals 12 damage per second for 5 seconds to any enemy unit within 300 range.
If Bubonicus drops a corpse, it will serve as a short-sighted sentry ward until it is picked up again or it until it expires after 60 seconds.- Nuke - Corpse Launch
Point / Unit Targeted. Launches a spray of corpses at the large location, dealing damage and stunning enemy units that get hit.
130 / 155 / 180 damage, stuns for 1 second.- Escape - Death Void
Self-Targeted. Standard wind walk with a 20 second duration and 110 second cooldown. 75 bonus backstab damage just like the original.- Heal - Consume
Self-Targeted. Consumes a stored corpse in order to rapidly heal Bubonicus and other nearby friendly units in a small area of effect. Feeding on flesh drives units effected into a frenzy, increasing their attack and movement speeds temporarily.- Unique - Exhume
Passive. Raises Bubonicus's corpse storage to 5. Bubonicus can now replenish 1 corpse every 45 seconds on his own. For each corpse that Bubonicus has stored, he gains an additional 1 armour.- Ultimate - Meat Shield
Self-Targeted. Consumes all stored corpses in order to form a meat shield around Bubonicus.
Each corpse absorbs 500 damage before exploding into a cloud of toxic gases. These clouds linger for 10 seconds, and lower the armor of enemy structures and units caught inside by 5.
His minions would presumably have some way of transporting corpses to assist in sieging, but would not use them for themselves. The main idea would be for Bubonicus to be a powerful sieger but weak in scouting and hunting due to a weak escape ability.
@TooNoobForU also suggested replacing Bubonicus' old Corpse Launch nuke to a form of a hook (such as Pudge). I've included this option in the poll.
