Seeing the green dragon, which the Druid had turned into, return to an undamaged state, Roland knew that things were far from good.
Morphing into a magical beast did not make one as powerful as the original beast of the same level. However, a Druid could rely on nature spells to make up for this.
In addition, the advantage of Morph was obvious: one could obtain a new intact body by switching forms.
This was why when fighting a Druid, one must kill him in a short amount of time, or else once he switched forms, one would have to fight a "brand new" enemy.
However, Druids were not without weaknesses. The interval between Morphs was at least half an hour, and no matter how much a Druid changed, their soul was unchanged, which meant that mana was always depleted. So if there was no way to kill a Druid in a short period of time, it would be a good idea to find a way to drain their mana, or attack their soul with spirit magic.
