So my current build is useless?
Was your current build the Mantra spam one?
Here were the changes I made to make the switch as painless as possible to a WoL build:
*Aughilds Chest and Bracer
*Leoric's Crown Helm for the CDR (if you don't have SWK amulet, otherwise keep SWK head, shoulder and gloves but have a very good Amulet to make up for it)
*Crimson's Belt and Pants
*Crudest Boots with WoL attack modifier
*Grand Incense Torch for weapon (very important)
Take out any extraneous stuff that had attack speed and replace with resource cost reduction. Also redistribute points from Paragon points away from Attack speed and into RCR. Attack speed is useless now. This includes your RROG, gloves and amulet if applicable.
Then pick Element for what you have on those slots. Physical, Lightning, Holy and Fire are all very good Bell builds especially starting out.
If you choose to go Fire then you can use Cindercoat + Strong Arms/Reaper Wraps instead of Aughilds which can allow you to pick more offensive passives rather than having a bunch of skills designated around Spirit regen. It will however be very squishy.
Alternate build with Inna's set + Reaper's Wraps or Strong Arms:
Inna's Chest, Pants and Helm. Belt you use Witching Hour.
Inna's 4 piece allows you to have all Mantras (freeing up a slot for a Mantra) and more importantly the lowered cost of SW allows you to stack up Taeguk very quickly and freely.
Active Skills: Epiphany (for Spirit regen and defense or offense), WoL, Dashing Strike, Mantra of choice/ Inner Sanctuary, Monk Ally (for Spirit Regen), Sweeping Wind (for Spirit regen)
Passive Skills: A spirit regen, one defensive, Beacon of Ytar and one offensive gets the job done here. You don't need any passives that build attack speed anymore.
Gems: Taeguk, Bane of Trapped (works with the taunt effect now) and Bane of Powerful. Gogok is still usable if you want to reach a certain CDR.
The build is basically spam Bells as much as you can while having full stacks of SW up and using Air Ally to fill up Spirit as needed. Basically you can spam a ton of Bells before needing to top up. With good CDR you can have good uptime on Epiphany and during Epiphany you don't even need to use Air Ally so save that for when not in Epiphany mode. Dashing Strike to move around and position yourself. SW and Mantra are useful to have max stacks of Taeguk up all the time.
You can still use your current build just replace some skill with the Holy Bell and just spam builds, attack with generator when low in Spirit. This is still good enough to beat T6 easily.
In Season 2 having Exploding Palm in the skill rotation is going to be huge due to the Gungdo Gear item. But for now keep off EP.
A build with LTK is also viable though not as powerful as the Fire Bell build (GYK Helm, Maximus, Cindercoat). Tempest Rush build is also very strong with the Cold rune.
Edit: Tzo Kin's Gaze (the one that puts WoL on the enemy) is also very good to have now because of the WoL damage bonus and it being a safe option against some Elite types.
