Dorothy will be our first 6 Specialist [Trapmaster] , an archetype that deploys traps onto melee tiles that trigger when an enemy comes within range. Unlike summoners, traps do not take up deploy slots, but they also cannot be deployed on a tile that an enemy already occupies.
Dorothy’s kit can serve multiple purposes, depending on the skill used. When using Skill 1, the traps deal physical damage and reduce enemy defense, a potentially useful tool for physical damage buff/debuff strategies. When using skill 2, the traps deal physical damage and bind enemies, with the bind time increased if there is only one enemy affected. This skill looks very similar to Magallan’s skill 1, which is arguably her most effective meta skill. Skill 3 looks like it came straight out of Bomberman. It does AOE arts damage in a long cross shape while also slowing any enemies hit. This skill looks like it could be visually and tactically fun to use.
For units like this, it is very difficult to predict their impact on the meta. They typically represent alternative styles of play which can be very fun to players that are interested, but tend to not be incredibly relevant for high difficulty meta. They do seem to be more relevant at times for more general content, or some of the alternative game modes, like integrated strategies or FAQ.
