TH12: Grudge Bow "The Bow of Genzanmi Yorimasa" only has 2 phases selectable, not all 4

[toimine]

@webbedspace webbedspace commented on 12 Nov 2021 This spell has 4 phases, each separated by a cancel:

• Sparse fast bullets from alternating sides
• Dense slow bullets from both sides
• Sparse fast bullets from both sides
• Dense medium-speed bullets from both sides

Currently you can only select phases 1 and 4 (I think).
