Thank you for such a detailed reply, Kalibano... and yes, it has helped as you detail and explain things extremely well
I'll detail the reasons behind my choices and explain how your reply has helped me.
Why Artificer Renegade Mastermaker and not, for example, Battle Engineer for a hybrid melee/caster?
Survivability: +6 CON, +90 health from cores, +30% (approx) health, Regenerate SLA, self-repair "HoT" and a cleave (i don't go for the INT based abilities from the RM tree). For a chain build, I don't see much synergy from BE to be perfectly honest.
DCs... I cannot agree more with what you wrote, and your explanations above in this thread are extremely clear and detailed. And here comes the first point where your reply has seriously helped me; Carrion Swarm does not do more damage than Dragonbreath and I miscalculated it in my head... just ran the numbers in a spreadsheet and DB is about +20/25% more damage depending on which reference you take (DB or CS). I also take on board the utility of the Daunting Roar 25% paralyze ability which coupled with a 3 second CD vortex around player must be very good. For info, does Energy Vortex still fail if initial tick has not targetted an enemy? Must keep that in mind! Also, and here I forgot, Carrion Swarm now has a hugely disappointing save which as my build's DCs will struggle, wouldn't be optimal. You have convinced me to change epic strikes! IIRC (and that doesn't happen every week) Shard Storm has no save? I'm also now thinking of dropping Tactical Detonation and taking Deadly Weapons instead. Ugh!
The reason I would (and am planning to) go T5 Draconic Incarnation is for the non save Ruin and Gruin spells; sure they are expensive at 75 and 150 spell points a pop, even before meta's are added (65 extra with all 4 metas) but that's where not spamming them unless totally needed and with extra 340 temp spell points for 1 min from improved Wellspring plus the frequent +100 temporary spell points from Ever Green come in very handy. Coupled with DI's cores, a few EDP invested into meta cost reduction, it is easily manageable, i find.
My (so far) revised build is 15 arti 4 Alch 1 Rogue (I built this one in my head and started with 2 rogue for evasion and totally forgot about losing access from RM T4 extra CON/MRR ability). 4 Alch provides an extra feat which i may copy your approach and take Battalion Brew as a cheap (AP) option
I realise that your build has far more cc, and for good reason as you have clearly explained earlier in this thread) but I think mine will be fine in terms of melee DPS with the imbues and the 2 chain attacks.
What you did however make me sit up and take notice was the choice of going down the shield mastery path... i reread your OP and ofc you underline the reasons why you used a +1 Heart of Wood for level 1 feat choice (what's worse is that deep down I already knew this) by swapping out rogue from SDK. I thunk about this, then rethunk more, and i may be leaning towards SWF and ofc taking a rune arm for the extra weapon damage mostly. I also have read on other threads the benefit of taking SWF with a chain build but tbh I don't understand why. Do the 3 attacks occur slightly faster and therefore slightly reducing the cycle CD respectively? Please explain as you would to a slow child. Thanks!
So, my version will be a "tanky" toon, but not a tank. My role will be a trapper with immunities (similar to yours) excellent self repair, good health pool for a first lifer, displacement and 2 chain attacks oozing with poison imbues. WIll probably need to spam Tensor's Transformation. I quickly reshuffled my heroic AP spend on the train back home and now I'm going to spew it out here:
RM 36 (+2 INT)
VKF 13 (+1 INT)
SDK 18 (+1 INT)
VC 17 (+1 INT)
I will lose 3 imbue die from Assassin and the Harper Agent Trance (boo).
I have abandonned all thoughts of needing high DCs (i woke up!).
I have changed my feat selection:
Heroic (11): Quicken/Max/Emp, 2 constructs, BB, SWFx3, Precision, Improved Critical
Epic: Wellspring, Intensify, Ruin, Gruin, Blinding Speed (as before)
Destiny: Perfect SWF, Doublestrike, Harbinger of Chaos, Titan's Blood +1 (now thinking about Arcane Warrior!).
Thanks again for your help.
