# Explain why it's good for the game
For a caste that is supposed to be a direct counter to preds, the main
ability is underwhelming and borderline unusable unless you have a
number of hours fighting pred with warrior already, this isnt even
including the fact that said pred is running around with a plasma rifle
not trying to get near you

With all the risks you are at for just existing, your entire moveset and
counter potential of a caste that is rare to normal play, and the fact
that you can just not be experienced in warrior to get a role of
predalien, I think its fair to have 0 delay if you miss feral smash
along with more reward

# Changelog

<!-- If your PR modifies aspects of the game that can be concretely
observed by players or admins you should add a changelog. If your change
does NOT meet this description, remove this section. Be sure to properly
label your changes in the changelog. Please note that maintainers freely
reserve the right to remove and add tags should they deem it
appropriate. You can attempt to finagle the system all you want, but
it's best to shoot for clear communication right off the bat. -->
<!-- If you add a name after the ':cl', that name will be used in the
changelog. You must add your CKEY after the CL if your GitHub name
doesn't match. Maintainers freely reserve the right to remove and add
tags should they deem it appropriate. -->
