What is the server tick rate for Ragnarok Online?

[BseeS]

Skills like Firewall suggest tick rate of 50, which seems extremely high for a tab-target MMORPG.

Officially, Ragnarok Online has a interval of 20ms.

If you use rAthena, you can customize the intervals for different things yourself by adjusting some constants. A while ago I set the base timer interval to the official value by default.

// If the server can't handle processing thousands of monsters
// or many connected clients, please increase TIMER_MIN_INTERVAL.
// The official interval of 20ms is however strongly recommended,
// as it is needed for perfect server-client syncing.
const t_tick TIMER_MIN_INTERVAL = 20;
const t_tick TIMER_MAX_INTERVAL = 1000;

Examples:

- Unit skills like Firewall and Heat can hit 50 times a second if there's no knockback

- Skills with an interval not dividable by 20, such as the interval between each waterball hitting will alternate their delays (in case of waterball it's 140->160->140->160 instead of 150ms)
