If your Mage would like to deal a large blow but not kill the boss at once, they can monitor how much damage they're dealing using the Data Display Tool. They could check that after every few castings of the skill, and when enough damage was recorded, they could stop casting. Note that the damage would still be applied to the boss on the next day; that tool just reports on how much damage there will be. Once your Mage is familiar with how much damage each casting does, they can count clicks on the skill instead of using the tool, if they find that easier. As they become stronger, the skill will do more damage each time, so they might want to check back with the tool every so often.

My point about cron was related to avoiding damage to party mates. If you know who is going to kill the boss (and we do, because we report it in chat) but you don't know whether they'll cron before you or after you, you'll still do your Dailies because you want to avoid the risk of damaging your party mates if you happen to cron first.

And of course there's still a point to doing your own Dailies so that you avoid damaging yourself. There's still a point to doing your To-Dos because it gives you gold, XP, and drops. Killing bosses isn't intended to be the only motivation in Habitica.

One thing our party sometimes does is share the damage between players. One player will report how much damage they've done that day (obtained from the Data Display Tool), and then another can decide to cast enough skills to make up the rest of the damage required to kill the boss. In that situation, the first player's damage definitely counts, even though they don't kill the boss themself.
