Uh, Gleam is rather easy to come by. Maybe not so much the red, but everything else is readily available. If you feel like you just aren’t strong or brave enough to get it off of a higher Tier Planet, then there are shops that have it fairly priced. It’s not fair to limit block use type for the majority of players who DO have it, just because one or two people haven’t found it yet. Especially when most builds using it are already complete…
If you need some that badly and can’t afford it, ask. Both myself and others would gladly help donate blocks for the event.
