At once that monster changed its attitude and all his hands showed a variety of huge strange-looking weapons which were directed to this rune trying to smash it. Ibro felt lucky.
If he threw his normal rune then this attack would be more than enough to damage his rune. All the weapons landed on the rune at the moment of its explosion but they failed in stopping its power from engulfing that monster.
Although that power was slightly weakened by that monster massive attack but it was enough to threaten that monster. The monster didn't stand like before doing nothing, but his scales suddenly enlarged to cover its whole body with thick layers of defense.
That rune power started to attack that scaly shield brutally. Ibro knew that his single rune effect ranged from 30 seconds to 1 minute. But after the attack of that monster, he didn't know how long it would be.
