They were hidden behind an urban crawler that I was fighting and it was crawling with other creeps around it. I was using leafy whip due to my +40% earth enchant. Boom, out of nowhere, instadeath.
I know that you can avoid these by not using a background damaging spell, but does a new player know this? Also, do they have to be instant death if you make that mistake? I wouldn't mind if they were like other traps and just damaged you substantially. But this instant nuke is, tbh, unfair.
I'm not arguing their existance. Just their singular ability to instantly blow you to kingdom come without any forewarning what so ever. I may have been in the beta for ages, and I even knew about these barrels, but had forgotten. A new player have no chance of knowing this.
Simply turning them from "Blow it up and you're dead" to "blow it up and you're in dire straits and need to run" would make a world of a difference. For reference, my max health is around 700 or so, so I wasn't exactly running a squishy either.
