How reason retrainers cant venture for clusters?

[OwlBlackX]

Retrainers can farm shards and crystals.

Cant farm clusters. How reason cant?

If I came lazy or not mood farm clusters myself. When my clusters runned out from crafted.

I wanted send my retraienr farms clusters

You should look into aetherial reduction

I had unlocked aetherial reduction long ago.
But never use it, I was not idea how.

I used myself gather clusters in Mor Dhona.

Retainers can only gather from normal nodes. Clusters are currently only available from Unspoiled and Ephemeral time locked nodes which is why they are unable to be exchanged for ventures.

While you can't send them out to gather clusters, they will on a rare occasion bring back a cluster or two from Quick Ventures..... But that is in no way a reliable method of restocking cluster for crafting.

The best method is Aetherial Reduction, just have your web browser on Garland Bell (https://garlandtools.org/bell/) and set the notifications for the Ephemeral Nodes, so you get the time frames to go to the zones and start gathering Collectable Reducible items to then reduce for the crystals/clusters you need.
If you still do not know much about Aetherial Reduction, it's basically get an items collectable value to up to less than 70% of its max, then when you reduce it, it has a very good chance of dropping clusters instead of sands. Too low a collectable rating, it just drops crystals, too high and it will mostly just drop crystals and sands, but in the middle it's the best at clusters. Clusters take up the spot of sands in it's loot, but sands is dependent on getting the collectable rating high (higher rate = much higher chance sands will replace clusters). So, if it's too low for sands to drop, then clusters drop. The higher the rating within the "cluster window" will also mean more clusters. While it is still possible to get clusters from a max rating, sands tend to displace it much more. (NOTE: The reduction will always drop crystals and if the rating is high enough it will drop crystals and clusters or crystals and sands, but never both clusters and sands at the same time)
If you're lucky with reducing and also manage to efficiently hit the node during it's spawn window many times (yeah, chug that cordial...) you can get a couple hundred clusters in around 10~20 minutes, plus double or triple that in crystals. Any sands that drop you can either use or sell on the MB.

Second best method, of course, is Mor Dhona, and using the two gathering skills to increase shards/crystals/clusters amount, with a third gathering skill to increase item count by up to 3.
A max level you can typically get about 100+ a node with good RNG.
