Inns, and hotels, are special places that players can save at to respawn when they die. Inns are unique in that they offer full HP/SP restorations via the innkeepers (localized as inn employees, inn staff, and inn master on iRO). Inns are available in almost every town and city in Ragnarok Online, but are oddly absent in Ragnarok Online II.
Because the developers gave Kafra employees, Zonda agents, and Cat Hand agents the ability to save a player's spawn point, inns have become largely obsolete in both RO and RO2. Nevertheless, there are still players that appreciate the overall novelty of Inns for their place in MMORPGs.
