- The slow from
will not stack with items, such as , or .
- Their slow will be applied instead of Rylai's on targets affected by Rylai's 15% slow.
- Deathfire Grasp's active ability will apply the 35% slow from Rylai's.
Spammable single-target spells only apply the 15% slow. The reason for this, as stated by Guinsoo, is: "We don't want a 35% slow that can be reapplied indefinitely." Currently, the only ability affected by this is 卡西奥佩娅的 Twin Fang. Conversely, 卡尔萨斯的 Lay Waste, despite both being an AoE spell and having an extremely short cooldown, applies the full slow, but only if it hits a single target.
The general rule is that spells with a base cooldown of less than 3 seconds will apply only the 15% slow.
The following will not apply the slow:
- Champion abilities that don't apply spell vamp
- Magic damage on-hit effects from items
- 黑默丁格的 H-28G Evolution Turret
- Rylai is the name of the Crystal Maiden hero in DotA. Rylai specialized in using ice-based crowd control abilities to stun and slow her opponents. The icon for the Crystal Scepter is almost identical to the icon for the Crystal Maiden's Brilliance Aura ability.
