Thousands of MMO players wage the ultimate war in a race to break their game: infinite money vs infinite inventory space

Old School RuneScape is knee-deep in its latest game-warping League event, Trailblazer Reloaded, and this particular limited-time mode has sparked a fierce feud between players that's quietly become one of the most interesting races in MMOs right now. 

OSRS Leagues basically make the MMO play way faster – better loot, more XP, and so on – for a two-month hit of adrenaline and dopamine. For this League, that's largely thanks to the unlockable Relics acquired as you complete tasks worth League points. Relics can be passive or active bonuses that essentially buff certain skills, actions, and play styles. Trailblazer Reloaded, the fourth League event, features some especially spicy Relics in the endgame, but the biggest player divide has actually come from two early-game Relics: Fire Sale and Banker's Note. 

Fire Sale lets you get anything sold by item shops for free, provided those items would normally cost gold and not another currency. This includes a wealth of equipment, crafting materials, magic runes, and other invaluable resources. You can't sell these items back to shops for instant cash, but you can easily buy high-value items and turn them into gold using alchemy spells. This gives Fire Sale users a never-ending cash stack and unlimited access to almost anything sold by NPCs. 

Banker's Note, meanwhile, ties into the OSRS bank and inventory systems. With some notable exceptions, most items can only be stacked in your inventory if you convert them into notes at a bank, but noted items can't actually be used. If you noted two chestplates, for example, you could carry them in one inventory spot, but you wouldn't be able to wear either of them without un-noting them. The same goes for drinking noted potions or eating
