 * As a Nyx, throwing several Castanas to the floor, casting Absorb on top of them and detonating them makes a good (and fast) combo for an instantly "charged" Absorb with the right build.
 * Mirage's Hall of Mirrors can be used to increase the number of Castanas that can be planted, but the holograms' Castanas will detonate a few seconds after impact; though they will not damage the player and can still also be detonated manually in the given time they are active.

 * Note that as of, the Link + Blessing Combo is less effective, due to the fact that Blessing doesn't confer invulnerability any longer.
