Reactive Blink

9th-Level Alacrity Feature

When you are the target of an attack hit or miss you may use your reaction to teleport away to one of your blink markers. If the attack beats your AC or you fail the appropriate saving throw you still take the effects of the attack or spell but it does not stop your teleportation. ie if an owlbear hits you with its claw and rolls a 25 to hit thus hitting you, you still take the damage from the claw and teleport away which may save you from any further harm of the enemy.

It must be the size of the palm of your hand. example dagger yes. arrow no. work with your DM on small items to make sure they are ok with it.

It takes a bonus action to place a mark on something and it cannot by removed except by magical means. Dispel magic, disintegrate, etc. You must have a straight path to your marker to teleport to it you cannot go around walls or cover ie line of sight needed. and require space to do so. You immediately appear in a 5ft space adjacent to your marker if no 5ft space is available the teleport fails.
