Branch affected by issue

base

Steps to reproduce

Using the same Songs+ bonus (say, gjallarhorn_75) for each cast:

Cast "Fire Threnody" -> Fire Threnody takes effect Cast "Ice Threnody" -> No effect

Code is already overwriting if the bonus is different between casts (example: going for gjallarhorn_75 to gjallarhorn_99), just need to change this specific case.

Expected behavior

Cast "Fire Threnody" -> Fire Threnody takes effect Cast "Ice Threnody" -> Ice Threnody takes effect

Retested on retail. First 2 casts are with Ghorn (Songs +4), 3rd one is with Marsyas (Songs+0)
