I run 75 in Ele (14%), 78 into Erosion(5024 spell pen), 81 towards Master at Arms (24%), and 16 into Thaumaturge (7%).

Some people like to drop it toward flatter values like 10% in Ele, 20% in Master, 10% in Thaumaturge, 5000 toward Erosion, and then distribute the remaining points out amongst Blessed. Elfborn, and Shattering Blows.

Overworld content has 9100 resistance and bosses have 18200 resistance in trials/group dungeons. Having light armor gives you 4884 penetration and 100 as base so 4984. 5024 extra penetration in almost every scenario is too much placing you at 10k penetration. You should aim to have 8-9k pen as a base, because with major/minor breach and other debuffs in a group environment, you will over penetrate, but at least at 9k your doing full dmg solo without the need of major breach on your skill bar.

So yes.. imo 78 in cp erosion is too much, especially if you don't want to change your cp around for every little bit of content you do. ALSO, diminishing returns.

I'd go with this setup for most scenarios.
44 Thaumaturge (17%)
56 Master-at-Arms (20%), 19 Staff Expert (12%)
49 Elemental Expert (11%), 44 Elfborn (17%), 38 Spell Erosion (3250)

Remember, cp adds together for the same dmg type. A light atk would be calculated like this (master at arms 20% + elemental expert 11% + staff expert 12%). Aka: 43% for light atk's, investing 75 points in to elemental expert will give only 3% more then 49 points, you could take that 26 cp points and invest them in different areas to focus on a dmg type that gives more return.

Gotcha that sounds like a good set up ill give it a go. Yea that much erosion would be for something like vma or soloing dungeons. Ill give your a go and see if it helps me get higher currently parsing around 38-39k want to break 40k

If you want to be technical about it and get the exact numbers you should invest in, you can pull up combat metrics with a 0 cp dps parse. Check out your dps for each skill.

So for example: as a stam sorc.
40k dps parse
6k endless hail (15% of overall dmg) -Thaum
6k relequen (15%) - Master at Arms
4k light atks (10%) - Master at Arms + (physical weapon expert)
2k poison enchant (5%) Master at Arms
2k hurricane (5%) Thaum

ETC.. by the time your done, you can say.. alright. 57% of my dmg is Thaum, 43% is master at arms and from that 43% of master at arms I have about 10% from light attacks. 100% of my dmg is affected by mighty.

Now what % of my dmg can crit? Relequen and my monster set can't crit, so that accounts for about 8k of my dps (20%). Therefore when I invest in to crit dmg, only 80% of my overall dmg benefits from crits and thats if I had 100% crit chance. Lets say I have 60% crit chance, so that 80% of my overall dmg now changes to 48% of my overall dmg. Remember you start with 50% additional crit dmg as base and lets say minor force is up 100% of the time so your always at 60% extra dmg with crits. CP will only increase that modifier from 60% to 77% and with that it only affects 48% of your dmg done.

So as a stam sorc, I always have my cp in crit dmg at around 16-19% because it's about half my dmg.

100% of my dmg benefits from mighty. 49 cp = 11%, while 64 cp = 13% dmg. That 2% doesn't get lowered like crit dm does because all dmg I do is within that dmg type. With 16cp I gain 2% dmg. 0.125% dmg per cp point.

57% of my dmg benefits from thaumaturge. 44 cp = 17%, while 66 cp = 22%. Thats 5% dmg that gets lowered because of the 57% equaling out to 2.85% of total dmg. With 22cp I gain 2.85% dmg. 0.130% dmg per cp point.

This is just a rough idea, but it's to illustrate how I gain more from thaumaturge even though it is only 57% of my dmg vs something that affects everything. Changing your cp based on how your build operates comes down to you to get that EXTRA bit of dmg. My guess is thaumaturge is pretty potent on a magdk. So I would take a little from Master at Arms or Elfborn and put it towards Thaum.

Also 75 cp in the middle tree gives 5% extra light/heavy atk in execute range, I'd try to keep that passive.
