I propose that the bombhead masks that are currently only obtainable through bribery be craftable. The recipe could be one of the 150 token masks + some mats and each mask upgrades into a specific bribery mask. Seems pretty fair and simple as it would require some amount of blast network play. The recipes could be autoloaded into that king krogmo alchemy machine. Also if rarity is an issue there could be a 300-500token template mask that can be upgraded into any of the bribery masks.

This may not be the best fix but I have been very active on this game and those bribery masks seem near impossible to acquire. And although I can agree if there intended to be rare I think any given player should have a reasonably fair chance to acquire one especially if their active in the pvp arena.
