It's multiplicative, if it's additive then the number would be overkill. 3009% star absorb for Raikou is WAY above even rider 250% average which is ultra overkill.

Due to it being multiplicative Raikou number can reach a reasonable number of 9 x 30 = 270 which is higher that Rider but  still reasonable enough. If the skill are additive then nobody will ever get the stars if Raikou used her 1st skill due that absurd 3009% star absorb rate,, however in fact there's some star slipping here and there once in a while means we can cross out the idea of additive from this evidence.

I am not sure what do you mean that the skill will work better than class of Rider/Archer but personally it used for 3 things

1. Star distribution control : MHXA have innate low star absorbtion courtesy of being Zerker, so if you could give 1 party member a pseudo star gather up by lowering the 3rd member star gather down using 3rd skill.

For example you have MHX, MHXA and something like Chloe. At normal circumstances MHX and Chloe would have tug-o-war of crit with favor goes to Chloe, but by using 3rd skill on Chloe MHX can easily get all the stars.

2. Star gather reversal. note this is extremely rare case but in event where you have someone with star absorb up skill that "pollute" the pool then you might want to use this skill.

for example we have Lancelot with 2nd skill active but at the next turn he only have 1 cards that absorb 10 critical stars that you don't wanna use. at event like this driving Lancelot basic star absorb to 0 will override the star absorb so you reset the star distribution for that turn only.. a rare occurence but I've done it at least twice so far.

3. simple buff. using MHXA as the target won't alter the star distribution much and it function as mere 20% atk buff which is nice by it's own.

Note that the problem of OP is that he forgot that Zerker base star absorb is 9-12, this means it's barely above 0 so using the skill hoping for MHX would crit is not reccomended
