Construction is trained by building with planks — each build consumes one plank and grants instant XP: Plank (level 1, 29 XP), Oak Plank (level 15, 60 XP), Teak Plank (level 35, 90 XP) and Mahogany Plank (level 70, 140 XP). High Construction also unlocks permanent perks: the Money Purse (level 70) lets you spend coins directly from your bank when shopping; at level 80 gathered loot banks automatically when your inventory fills during idle and offline play, so long gathering sessions never stall; and Master Rejuvenation (level 90) refills your special attack bar to 100% whenever it empties, in solo fights, group bosses, raids and the open world alike (but not in the Wilderness). Perks are managed on the Character Unlocks screen.
