Official RuneScape Skateboard Decks by ex-Mod Soffan

Grind in game and in real life with this RuneScape Skateboard Deck. Featuring artwork from a former member of the Jagex Art Team: Mod Soffan who has illustrated the three-headed boss The King Black Dragon clutching a glowing Dragonic Visage and the final boss of the TzHaar challenge and the Ancestral Glyph that imprisons him. Designed for adventurers, collectors, and skaters of Gielinor, this deck brings the world of RuneScape to the streets.

Art by ex-Mod Soffan. You can pre-order real versions of the decks at the official RuneScape merch shop.

Install and enable the mod in ReSkate. Select the matching deck graphic and grip in the board customizer to use both sides.

Install RuneScape Decks

You need ReSkate and your own copy of skate. on Steam.

Open ReSkateLauncher.exe and go to MODS.
Search for RuneScape Decks and click install. The launcher also installs anything it depends on.
Press PLAY. In game, the MODS tab of the ReSkate menu (Insert) turns it on and off.

Or install it by hand: download the .zip and drop it on the launcher window, or unzip it into its own folder in Mods\ beside Skate.exe.

Maps show up in the ReSkate menu's level list. To join a server running a custom map, you need the same map installed. If the game won't load after installing, see known issues.
