Just sharing my thoughts, feel free to disagree.
In the first place, a Zealot really does not āneedā monk in the build. With good investment, a Zealot can do most content with Krivis3 and Zealot2 alone with its buffs and AoE capabilities. Monk and Krivis/Zealot relies on different stats (DEX vs SPR/STR), and the only reason to take both is because Zealots can deal the highest DPS that way with Monkās bossing damage (subject to DEX and ping). For bossing damage purposes, Monk 3 Strike duration really helps (iirc Double Punch Strike debuff is about 3-5 seconds, likewise for God Finger Flick? I forgot) when bosses run away/get out of reach and to keep up strike debuffs.
Zealot has good AoE capabilities for a physical cleric build, so its no wonder no one uses Energy Blast, a less-reliable linear AoE. IMO as a monk zealot, you can skip Energy Blast if you so wish for it. It takes a lot of investment to even make it decently useful. Golden bell shield is rather situational, but it has its uses for setting up buff/emergency oh-crap button to use while safety zone is down.
With that said, speaking as a monk (before zealot came out) who went crazy with T10 Skull Breaker, lvl 100 Double Punch and Lvl 100 Energy blast,
I used to do ET with 3 Cryo-Chronos (or 2 Cryo-Chronos and 1 Hunter3Falcon3) and 1 Taoist as a Monk 3 and carried DPS floors alone (via Frost Tree > Energy Blast > Pass > Rinse and Repeat for mobs, God Finger Flick > Combo to Double Punch for bosses) up to 35F, and with that I can attest Energy Blastās usefulness back then, albeit expensive and with party help.
Then again, with a reliable AoE skill set in Zealot, Energy Blast is no longer needed as an AoE skill, and Energy Blast is just simply very situational now to warrant any skill points other than for fun (cāmon, Energy Blast looks awesome), or for knockback purposes with 1 point.
Feel free to skip Energy Blast.
