The first ten terms sum to 2.68. I get around 2.86 with ten million terms, off by a factor of 2.

I would expect 14+ to take something like 3x base cost and time (oh, divide that by 2 with 10+ as your baseline?).<br /><br />Yeah, we've never really considered apprentices viable; our 5th-6th level casters have enough trouble getting any research done. I really like having apprentices add a bonus to the master; I think that would make them worth using.<br /><br />I am explicitly not worried about preserving the continuity of projects / I like the idea of freely stopping, starting, and switching projects a lot. It's a poor simulation of real research work (because, like, mental cache effects), but v0v.jedavishttps://www.blogger.com/profile/08586249502818922886noreply@blogger.comtag:blogger.com,1999:blog-2657266526705426756.post-22738814388855401422017-12-22T17:25:32.263-05:002017-12-22T17:25:32.263-05:00One thing I've done recently is to apply a sum...<br />One thing I've done recently is to apply a summation calculation to magical research - so that instead of binary success/failure, there's just extra cost and time applied to the process based on the magical research throw - so a roll of 14+, for example, means a potion takes you 1,429 of base cost and 1.43 weeks, ignoring the chance to fail in exchange for upfront cost.<br /><br />At 14+ the 85% success guarantee happens around the 8th roll; 99% around the 11th roll - so it's certainly advantageous; and it kinda approaches base costs at 4+ (588gp/.59 weeks, these numbers with with formula/sample)<br /><br />The other thing it kinda showed me is that L0 apprentices leveling to Mage 1 via successful magical research is expensive, evidently, anywhere from 20x-4x expected costs at the high MRTs. I've modeled apprentices instead granting a +1/-1 on a successful throw to the base caster's chances via summation, and then split the XP accordingly by individual successes, the main pool going to the leader; and it 'feels' ok, at least.<br /><br />The consistent summation process would grant some verisimilitude to projects one can stop/start; maybe with the requirement an apprentice has to watch the oven, so to speak; and it has the advantage of at least singing along with the default assumed costs of things, if not fully in tune.<br /><br />I've bookmarked your fork; I'm glad someone's thought to do it.Koewnhttps://www.blogger.com/profile/01417138644425141883noreply@blogger.com
