Took me a bit to note the new Shapeshifting effect... couple of questions to be safe!
-Does this replace the 'Alt Form' effect, or did I just have momentary blindness and couldn't find it?
-If the above is the case, I presume that the whole 'You can redistribute your essence minus Alt form costs' effect is gone?
-Say I want to buy Shapeshifting for Totoro, who has Ongoing Growth in his 'base' form: would I need to buy that effect a second time for my Shapeshift ability so my other forms can have that as well?
2) Yes, that effect has been removed along with Alternate Form.
3) Maybe, that depends on the Ability. Shapeshifting allows you to change into anything of your size category, so as long as the Growth Effect does not have a Modifier such as "Limited (Base Shape Only)", any of your Shapeshifts would also be able to be up to the size your ranks in Growth allowed.
If you did choose for some reason to stick a Limited Modifier on Growth, however, then yes, you would need to buy it again.
Well, first read the rules. Then create a character. Once it's approved... write. That's basically it. You could hop on the Discord and see if anyone wants a writing buddy, if solo stuff ain't your jam. You could also check out the Quest Board and see if there's anything there that sparks your interest.
