It doesn't work right . It should incrase 200 P def only when it is activated when it incrases to Level 1 + 200 P def , Level 2 + 200 P def , lvl 3 + 200 P def . Fully grown seed should be 800 P def . And Helaing Power each lvl it should be stronger.
Same goes for HellKnight , Shilen Knight and Eva's Templair . They all have seeds which doesn't work right .
