How to Get a Holo Sign: Frogdog Logo Decoration
Credit Decorations (previously warzone decorations)
The Holo Sign: Frogdog Logo decoration can be bought for 35,000 credits. It can be bought from a vendor in a room with a guild bank in the Crafting & Strongholds section of the fleet, NOT in the PvP section of the fleet. It does not require any special skills or PvP to acquire, just credits.
This item can be bought and sold on the GTN - beware of scammers and don't buy it from the GTN unless it is less than 35,000 Credits.
The Holo Sign: Frogdog Logo decoration used to cost 350 Warzone Commendations, but Warzone Commendations were removed from the game so now it just costs 35,000 Credits.
