Add suffix?

Hello,
could you confirm there are only 2 ways to add affixes on the chest below:
exalt the chest (add 3 randow suffixes)
or
add the master mod "Can have multiple Crafted Mods" + 2 suffixes

Depends on if the block/stun recovery is part of a hybrid prefix or a suffix or both. How did you get it to that point? Any rare generated randomly always has at least 4 mods. So if you got it there with a regal orb you have 3 mods left but if you used alchemy or chaos orbs you only have 2 mods left.

I don't know,I bought the chest
I spent 2 ex for adding the mod "Can have multiple Crafted Mods" but I can add only 1 affix
GGG should add some informations to indicate how many slots are available
