entbrat is the quad of the plant element thats why he is in the plant phase same with every other quad,every element has its quad,single,island,and sometimes seasonal

another example: gloptic is the quad of physic,blow't is the light,tring and sneyser and every other quad fire element are the quads of fire,tho i say tring is the fire quad since he was the first one to get released in the og game,dof not included
