Little Suggestion

1) Flag: add a function of destroying all other players' building in your base, but only worked in early game.

2) Slayer's Vault: add description about getting gold from middle of the map.
(Not like description about killing vamps or take vamps' items when they dropped on the ground carelessly or something like that.)
(Don't scold me when I write this because those newbies always ask where to get gold)

3) Gem Quality of Ultra Research Center: add some damage to comet / oracle towers also.

1) Flag means no one can build in that base. Not nesseccary.

2) Meh.

3) No. That is not the point of this upgrade.
