If the troll is given a speed boost, it will kill two more players. And if, for example, an Arghat remains alive, he can redirect it to a blocker, and this is just one of the options.

So, we agree that when Arghat sees the big and scary Troll, the mage, and a couple of elves, he realizes what he has gotten himself into, and releases Darin from his control, reforms, and vows never to do anything bad again, signs up for a staff psychologist, and disbands his army. Darin, seeing this, concludes a peace treaty with Silverwood and establishes trade with it on the most favorable terms for the kingdom. The Troll gets a Troll girlfriend and becomes kind and fluffy, the elves find common ground with him and arrange for him to be appointed an honorary citizen of Silverwood (together with the Troll girlfriend, of course), with a hut/cave/mansion under the palace/in the palace/very close to the palace/somewhere in the surrounding forests (at the Troll's choice). Sindin is left at the court, as the head of all the mages, Tanriel is made the head of the guard, if, of course, the elven kingdom does not object, and Leia... well, we need to find a place for her too, so as not to offend her... Does everyone agree?)))

Relax. In this situation, no one in their right mind would speed up the troll. But tying Arghat hand and foot while the gnome killer is resting (with the subsequent hanging of Arghat tomorrow) is quite possible. I advise you and Kostyakk to think about this.
