Regarding this thing:

I've had it in my armory for what feels like ages and, while my highest tier pet is only 11, I'm wondering if it'll have any use. How badly is it outclassed by other T12 weapons? Is it worth keeping around at all, or is it just gonna collect dust in the armory?

It’s more of a niche weapon than one you’ll use all the time. By that I mean it shines in specific circumstances. It has a negative heal on it, which means your HP will decrease each turn you use it, but it also does a considerable number of icons (58-65). For shorter battles or when healing is disabled, it will come in handy. Everyone has different preferences when it comes to battling so I would consider giving it a try before you sell it. You might end up liking it :)

It really suffers from the negative heal while most other t12 weapons will provide 10% heal. I think it’s more of a novelty than a practical weapon. It would get some use in battles with healing disabled since it does do a good number of offensive icons, but other than that, I don’t see it getting much use

These are both very good answers. Thank you! I'm still split on keeping or selling, but I at least know what I'm dealing with here.

I appreciate your time and answers, oh battle elders

I have a top 10 pet, and its one of the weapons I use the most.

I don't think it's niche at all.

I've messed around with the SRB to see if there were instances where it was really worth it. It does best in situations where you want to do max damage and healing doesn't matter. However, there are alternatives out there that can easily be used in the same setting that don't cost as much. For those reasons, I would consider it a niche weapon.

If you got it, great. Use it under the right conditions. If not, there are cheaper alternatives that can be used to do the same thing as it is not a necessity.
