Retraining barbarian to Invulnerable Rager

[Koraxs]

Hi all.
Need your advice.
Player-barbarian want to gain archetype Invulnerable Rager. How much days he will spent for that retraining?

By the rules
To gain an archetype that replaces standard class abilities you already have, you must spend 5 days for EVERY alternate class feature you would add, subtract, or REPLACE by taking that archetype. At the end of the training period, you lose the standard class features and replace them with the archetype’s alternate class features (if any).

In that case we have 2 variants:
1) Invulnerability (Ex)replaces uncanny dodge, improved uncanny dodge, and damage reduction.
So if read, that Invulnerability replaces 3 alternate class feature then player must spend 3*5=15 days.
Or
2) Player must spend only 5 days for taking Invulnerability as 1 alternative class feature, ignoring quantity 3 features what replasing.

What variant is more correct?

Fifteen, I'm pretty sure, but this is really a question for the rules forum.

5 days for every feature he currently has. So if he has uncanny dodge, but not improved uncanny or DR it is only 5 days. And if he has none of the features yet it is free to switch.

That makes a lot of sense, but is it strictly the rule? I think I'd run it that way regardless.

[Java Man]

It is the rule.

I'm not super sure on the retraining rules, but the archetype rules state that if the archetype you're changing to/from hasn't changed anything yet then you don't have to choose an archetype yet.

Invulnerable Rager would only have to be chosen when you reach level 2, because it doesn't change any features at level 1. If you're already level 2 then some retraining would be needed.

With that in mind it would be really strange if Java Man was wrong.

The operative section of the retraining rules:

Note that you don't have to use the retraining rules to take an archetype if your class level is low enough that the archetype doesn't modify any of your current class abilities. For example, if you're a 1st-level fighter who wants the archer archetype, that archetype doesn't replace any class abilities until fighter level 2, so you don't need to use the retraining rules at all—once you reach 2nd level, you can just decide to take the archer archetype.

Excellent.
