　　Some skills have a Casting Delay. A Casting Delay is a period of time after a player has cast a spell during which the player cannot re-cast that spell. For example, after casting Blizzard you must wait a few seconds before you're able to cast another one. The delay differs between skills. Not all skills have a Casting Delay. There is nothing you can do to reduce or eliminate the Casting Delay. If the Skill Action Button becomes red after casting a spell and you have enough Mana to cast it, this means the Casting Delay is active.
　　施展延迟
　　一些技能会碰到施展延迟的情况。所谓施展延迟是指玩家施展技能后，一定时间内无法再次施展这个技能。例如，施展暴风雪后，玩家玩家必需等待数秒后才能施展另一个暴风雪。不同的技能，有不同的情况的施展延迟问题。并非所有的技能都有施展延迟。想减少或杜绝施展延迟，是不可能的。如果施展技能后，设定好的技能键示意为红色但又有足够的魔法时，这表示施展延迟已经出现。
　　Tip: While you're waiting through the Casting Delay you can switch to another spell and use it while you're waiting for the first skill to be available to cast again. Example: Cast a Fire Wall (Casting Delay), then quickly switch to Static Field (No Casting Delay), then switch back to Fire Wall again. Once you get your timing right you can constantly cast spells even with a Casting Delay on one or both of them. Some Casting Delays are connected, such as the Druid's Armageddon and Hurricane, so you may not be able to combine two of the same type of spell.
　　提示
　　在施展延迟的过程中，玩家可能切换至另一种技能加以施展，直到前一种技能可再次施展。例如：施展火墙后，出现施展延迟时迅速切换至静电场（这时该技能没有施展延迟），再切换到火墙。一旦时间掌握得当，即使一个或多个设定过的技能都存在施展延迟，玩家都可以不停地在施展技能。一些施展延迟是相关联的，比如说特鲁依的Armgeddon和Hurricane,是无法联合使用的。
