This is something I've been working on a while, to see exactly what it took to hit 100+ strength, and what the maximum limit is. Lots of people ask about the breakdowns, and what stacks with what, and most get it wrong. (Pretty sure mine is accurate, but let me know if you spot an error)
So here it is, 100% verified ingame, ultimate maximum strength 100+ strength project / breakdown.. And challenge to see who can get it first =)
Maximum Strength Build:
Half-Orc Pure Barbarian 20:
Amount Type - Source
20 Base - Creation
05 Base - Level ups (4,8,12,16,20)
02 Race - Half-Orc Enhancement
04 Inherant - +4 Tome
02 Feat - Might Capstone Enhancement
02 Feat - Completionist
Permanent Equipment based bonuses:
07 Enchantment - Epic Red Dragon Helm
03 Exceptional - +1 and +2 bonuses on the Encrusted ToD Ring
02 Untyped - Frenzy Berserker III ToD Set Bonus
Increases to rage, so near-permanent
08 Rage - Mighty Rage
04 Rage - Power Rage Enhancement
02 Rage - Orc Power Rage Enhancement
02 Untyped - Madstone
02 Untyped - Double Madstone
06 Untyped - Bloodrage*
02 Untyped - Frenzy
04 Untyped - Death Frenzy
04 Untyped - Berserker's Fury Clicky
02 Untyped - Yugoloth Potion
02 Artifact - +2 Strength Ship Buff
02 Store - DDO Store Potion
02 Morale - Rage Spell
04 Alchemical - Fabricators Bracers (Non stacking with +3 House D Potion)
04 Profane - Hezrou Cookie**
06 Psyonic - Titan Cookie**
Grand Total at full HP: 105
+With Orc Fury (+6 Morale over Rage Spell (Morale) while under 10% HP)
Grand Total: 111
My total so far: 104 (Heh aparently 103 is the maximum the game can correctly display, any higher and it glitches out like this)
Other stackable sources that simply can't be fit in the same build:
03 Feat - Fighter Enhancement (Conflicts with Capstone - Might, Death Frenzy and others)
02 Size - Rams Might (Conflicts with Capstone - Might)
06 Insight - Kensai Power Surge (Conflicts with Capstone, Death Frenzy and others)
* Bloodrages ingame description is incorrect (or effect is bugged, either way). It states it provides +2, +2, +4 per level. But acutally provides +2,+2,+2 per level, for a total maximum of 6. Also keep in mind this is the most temporary and generally useless type of buff in the game, so it's not recommended and only listed for completeness.
**Limited seasonal item that may change next festivult.
The general rule is that bonuses of the same type do not stack. Here are some exceptions:
The following types of bonuses stack:
Base: Since the only source of base bonuses are creation and levelups, they always stack.
Untyped: It's unclear whether the developers simply forgot to include bonus types for these effects, or if they simply thought it would be more intuitive to not list them assuming players will understand they always stack.
Rage: Barbarian Rage has it's own special rule since it's an inherant class ability, which always stacks with everything, game lists it's type as "enchantment", but thats mostly incorrect since enchantment type bonuses don't stack.
Exceptional: Exceptional Bonuses only stack if they are of differing amounts. EG: +1 Exceptional stacks with +2, but not another source of +1.
Feat: Since feats are meant to be powerful, you can generally expect bonuses attained from them to stack. The game sometimes lists enhancements as feat type bonuses in the breakdown also - Ex: Might Capstone. There are some exceptions to this rule however none apply to this breakdown.
Keep in mind: Even tho these types stack, bonuses from the same source still do not stack ever. (Ex: If you had 2 identical rings with untyped bonuses to strength, they would not stack due to the way the game is coded they would be considered the same source)
No other types of strength bonuses ever stack.
