    - Retrieval
    - Quake
    - Spark
    - Thunderbolt
    - Shadow

- Increased damage of Burst & Thunderbolt by 1 (0.5 Heart) per level

- Rebalanced Icicle
    - Reduced Range by 25% (12 blocks to 8 blocks)
    - Increased Damage (0.6 -> 1 | 1.2 -> 2 | 2.4 -> 3)

    - Terraform
    - Hellfire
    - Quake
    - Thunderbolt

- Raised the damage of the Fangangler from 6 to 7 (don't laugh)

- Raised the durability of amulets from 64 to 100

- Elemental Masks no longer provide protection value
