Primal Savagery
Once per game, when Glotl fails an Animal Savagery roll, it may lash out at an opposition player rather than a team mate.
It’s a bit annoying for a star player to have a negative trait, in this instance its Animal Savagery. However this skill effectively lets you ignore it once per game. There’s not a massive amount to consider here from a tactical stand point. You basically have a couple of choices, either you’re likely to use it the first time you can take advantage of it.
Alternatively you might want to keep it in your back pocket should the situation arise where he’s being marked out of the game by an opposition player and you don’t have a team mate to spare to stand next to him. I think this might be the better play, especially as in other instances you can often have a high armour team mate to bite, though do bear in mind that Mighty Blow does get added to this or the injury roll.
