I was wanting to try them out and see how they are. In my solo game as soon as I come across one (and don't kill her) then I'll give her a try. In general, though, maybe my tactical strategy is still coming around, but I need to kill stuff as fast as possible, and if the bard doesn't really contribute to that philosophy, as the rogue doesn't, then I'll have to get rid of them.Bard is absolutely not useless and you can consider them a jack of all trades with some incredible good party buffs.
There is plenty of strategy in my strategy, but it doesn't call for a lot of sneaking and singing. But I'm not playing on the highest difficulty. If I did that, I might have to adapt a bit.
So far I've managed to keep fairly stocked with that potion from being frugal with it and just finding them around. Wouldn't mind having a lot more of them, though. I was out of health potions for a long time, but the place we are at now seems to restock them.Potion of hill giant strength helps my monk a LOT. It just needs some hill giant fingernails. I need to make friends with a hill giant tribe and make sure they get a lot of calcium.
The 9th level Ki Resonance thing is great! You hit them with it and, whenever you like, you can make them explode for 3-18 damage in a 5m radius. Dex save to half damage. Doesn't sound like a whole lot, but there's a trick: if you set up 2+ enemies, the explosion from one will set off the other. It reminds me a little of Dragon Age's "Walking Bomb" spell, but it has still another bonus: it doesn't hurt your party!
