Thorns of Agony

Description
Senses the pain of its bearer and lashes out at the world around them.

When taking damage, sprout thorny vines that damage nearby foes.

How to Acquire
Found in Greenpath in a maze of thorns. Requires Mothwing Cloak to reach.

Usefulness
The damage of the thorns is equal to twice the base damage of the nail (Fragile Strength will not affect this) and it also deals some knockback, however the AOE is rather small. The downside of this charm is that it deals damage without collecting SOUL and in some situations it may kill enemies otherwise easy to kill but will not yield SOUL.

For this reason, this charm is particularly useful when fighting multiple enemies at the same time, especially in the Colosseum of Fools.

Not recommended in Fog Canyon as damaging Oomas will make them burst, releasing their explosive core that homes in to the player, dealing high damage.
