Roblox WikiSummoning and shiny units
Gomu's Shiny Hunter description advertises a threefold increase in the chance of summoning a shiny unit. The catalog does not give the underlying probability, so it does not support an absolute shiny percentage. [4]
VIP summon discount
The VIP description lists 20% off summons, 10% more player XP and a rainbow name tag. It does not state which currencies or special banners are included in the summon discount. [4]
Unit storage
Unit Storage advertises room for 100 additional units. The description does not give the standard storage limit. [4]
Lobby unit display
Display 3 Units describes showing three units around the player in the lobby. This is a display feature; the description does not grant additional combat deployment slots. [4]
