The White Sentry immortal weapon is supposed to have a copy of all other animations, due to the staff having moving parts. When using CM's default animations, the staff visually breaks.

These are animations she has no copy for, so that the staff breaks:

1. Spawn
2. Victory
3. Versus screen
4. Beautiful Snowangel taunt

This means, when spawning, winning the match or using the snowangel taunt, the staff crumbles together and the eye moves into the shaft of the staff. The staff is not animationed. This may also be visible on the Versus screen.

This goes for her default model and the arcana model.
