With great attack, double strike, and a chance to reduce targets' defenses, Estrid has the potential to hit like a truck. Her ultimate can be slow while turning off the double hit, however, and with everything based on chance, she noodles a lot. Things get better with Awakenings, but most of it can be expected from the start. Late game Estrid becomes both an amazing AoE dps for GR5 and provides consistent high damage in Guild boss 2.
