Decos obtained from quests do not forward the Melder table - on my end anyway.doing a quest = skip 1
getting # of deco for quest reward = # amount of skip too.
example.
your list is as follow for the next few ritual.
A
B
C
D
E
F
...
Then you do 1 quest and you got 3 deco at the reward.
You'll skip 4 times.
Making your next ritual immediately after the quest:
E
F
...
The only thing I kinda stumble upon and have yet fully test out is, if i switch to a lower tier ritual (tier 2) and only put enough pt for 1 deco instead of 3. somehow if i go back to the tier 3 ritual on the next ritual, it act as the the previous ritual (the 1 deco but tier 2) counted 3 decos skipped.
But I'm kinda positive that each tier ritual has its own set of deco. they're are linked in sequence of other tiers tho.
Reminds me of the ruststone polishing in the old mh games lol. atleast in ps2 and psp. dont rember but think in wii they start to auto polish ruststone at the reward screen as a way to deter save scumming lol.
anyway to add to the deco skipping. like if you already planned your deco table out for atleast 50+, i guess the fastest way to skip is if they bring back that event where you get deco as rewards. its a quick way to skip alot of the deco sequence.
now if you want to skip only 1, il recommend you do like a easy low rank quest since if i recall, low rank quest dont reward decos at all. this way its a for sure 1 skip instead of more.
another note is that in the old mh, if i recall, only large monster quest skips the ruststone polishing. no hand in exploration ticket or mushroom delivery quest. not sure if its the same condition here or not.
Gathering quests work perfectly fine, I use the 4 fossil one. Takes about 35~60sec depending on your gathering RNG (geez lol).
