How to "open" a container

Not sure if this has happened to you guys, but currently I'm in scene 5 trying to get bent coin on easy with Yggdra as my heroine. I've been having trouble getting bent coin from the barrel since it needs to be opened. I followed Phalanae's guide but whenever I use searing edge the barrel gets 100% damage. I tried normal attack but it doesn't do any damage. Skill attack seems to guarantee a 100% damage on barrel. Any suggestion?

Are you playing in easy mode? Take note that in easy, objects have half durability compare to normal. If I'm not wrong, the barrel in B6 has 3300 hp in normal, so it will have 1650 hp in easy, perhaps that's why you break it in one skill. Try using your skill in a lower power charge% or use Lance Knight's Halberd instead. Hope that help...

Yea, I'm playing it on easy. I guess that's why it breaks even when I did a low charge %. Guess not all aspects of easy mode is that easy afterall...

better read up on damage calculation and figure out some alternatives. Personally I'm not yet used to the "not all units can move" "range is fixed". Still getting familiar with the game mechanism. Sometimes I got screwed up by height differences and other factors. But generally I like this game, especially the large cast of recruitable characters. It kinda reminds me of Valkyrie Profile.

Interestingly, the HPs of obstacles in each scene seem to increase, but not in the leveling stages. In the leveling stages, weapons are sometimes too powerful to NOT cause fragile states. In this case, repetitive normal attacks seem to be the only solution.

Obstacle's hp change depend on the mode that you're playing:
-Leveling mode: 25%
-Easy: 50%
-Normal: 100%
-Hard: 150%
-Nightmare: 200%
So if you're in some early stage, just rely on low damage skill or sometime even normal attack to open an obstacle. You can view each skill's damage when choosing a weapon, and combine it with a suitable L.i/C.I Knight for best result.
