-	description = "You lose your empower, charge, scissor cut and some slash damage, for a bit more explosive resistance, immunity to small explosions, and you gain several new abilities that allow you to become a spiky tank. You build up shards internally over time and also when taking damage that increase your armor's resilience. You can use these shards to power three new abilities: Spike Shield, which gives you a temporary shield that spits bone shards around you when damaged, Fire Spikes, which launches spikes at your target that slows them and does extra damage if they move, and finally, Spike Shed, which launches spikes all around yourself and gives you a temporary speed boost as an escape plan at the cost of all your stored shards and being unable to gain shards for thirty seconds."

Your resistance scales with your shard count and at 50% grants you immunity to some explosive stuns. You accumulate shards over time and when taking damage. You can use these shards to power three new abilities: Spike Shield which gives you a temporary shield that spits bone shards around you when damaged; Fire Spikes which launches spikes at your target to slow them and deal damage when they move; and Spike Shed which launches all your spikes, grants a temporary speed boost, and disables shard generation for thirty seconds."
