So it depends on the spell, but I think you are talking about summon nature’s ally. That allows you to give instructions to creatures who can understand, and they will fight to the best of their ability, but as a DM I wouldn’t interpret the spell as written to include suicide.

But even then, a good DM doesn’t put a tarrasque into play and have it sit there and die. Once it realizes it is getting damaged and can’t retaliate, it can burrow from we whence it came, etc.

So I think most of the strategies involve weak roleplay from the DM, munchkin builds, liberties with the rules, or both.

Even then, actually killing the tarrasque requires a wish spell, which is not something that a 9th level druid can do.

Yeah, I ran campaigns from first through 3.5, never really played 4th or 5th. I’m curious how 3.5 tarrasque is easy to beat with anything other than broken munchkin builds from conflicting source materials that no sane DM would allow, or would be reserved for epic level campaigns. Like sure, when you get to a point where you can casually cast things like hellball, then things like the tarrasque might be easy. But at that point you will be doing the tango with the outer realm creatures and Demi gods.
