For earlier dismantle spots - it helps to dismantle a high level turtle set glove - at level 4-5 it gives ~3000% armored attack. Basically try to maximize multipliers. A few thousand dazzle from upgrading the items you use doesn't help much I think. Also don't waste gems to convert items that aren't Divine yet (your helmet doesn't have the full 153% armor boost). Probably it's better to use the first 2 Divine Helmets on the boots and helmet - because of the double multiplier.
To avoid the problem with 'they don't have armor' - activate the first 3 challenges - it will also give you some extra gems. The time challenge might work for some too (for me this is kind of 'afk' game that I play on my second screen while doing other things. And the time challenge just doesn't make sense for a turn based game).
About the Jesters Mask - it doesn't increase Dazzle. It will increase only Wisdom / Eldership, but because of Empty Bastion - you don't really need it.

Shatterwave uses 'Physical Attack' to calculate damage (the tooltip is wrong). It doesn't work with Armored Attack. I've used the same build with Riel. But changed Shatterwave to Mimicry. I'm currently at level 157. Mana Steal might work too.
Another thing to notice - your inventory is kind of 'empty' :) The 'late game' phase the goal is to banish everything that you don't need, and fill your inventory with Divine items. When you open a chest - you get more Divine items - and when you combine them - you get extra gems. And you should use them on items for dismantling. If you get an item that isn't Divine - just sell it.
The 'dismantle spot' is every 25 levels, starting from level 10. At some point you should also buy omni crit scroll, max crit chance and dismantle the sword with crit damage - at level 4 or 5 it gives ~3600% crit damage, which is another multiplier that isn't utilized here yet.

there is a working guide for 100 floors per fren, after the last update?

How do you survive early/midgame?
