Doubts about training solo

1.) Yes, you can train both in the same thread. How I used to train (note that this was way back before the plot point system existed) was that I would split a training thread up into one post per technique/training target (i.e. if I wanted to train five different Kido spells in a thread, I would do like, an intro post and then five training posts, one per spell).

2.) There has never been a flat word count requirement for training techniques/masteries as far as I know, it's always varied on the quality of the work. It's been a while since I've done training, but I recall roughly 600 words being good for mid-level techniques if the quality is good, and obviously less for lower level techniques and higher for upper-level techs.

My best guess would be that your summons' techniques would have to be trained individually. Asfor how to app them, depends on if you're putting other techniques with it and how many. If you're just putting up one summon and its techniques, that can be on one app, but remember that each app has a 5-technique limit (i.e. the summon and their four techniques, of less if you so choose.)

Yes, summon techs need to be trained separately.
