Sorry very late reply, just leaving my thoughts for future players to think upon...I have tried to theorycraft such a build for more than one year already, and I kept coming to the same conclusion, that it needs too much ability/feat/spec point investment to work.
Shield Feats:
- Shield Arm
- Boarding Up
- Shield Bash
Spear feat:
Sword feats:
- Flurry
- Onslaught
- Parry
- Riposte
And since swords are meant for crits, crit feats:
- Recklessness
- Weaponsmith
- Cheap Shots
- Critical Power
- Survival Instincts
And since this build is a melee build, mobility is essential for melee, these feats will be very useful:
- Sprint
- Hit and Run
- Escape Artist
- Nimble - to reduce armor penalty for more movement points
- Body weight training - to reduce armor penalty for more movement points
- Armor sloping - to reduce the armor penalty of the steel plate that goes into the making of the riot gear shield
Other general survivability/QoL feats:
- Thick Skull - this build is stuck with riot gear, which is not the most invincible of armors. Getting stunned is most likely a death sentence.
- Sure feet - the acid from mutants and acid dogs will pool up around the character while fighting them as melee
- Ballistics - 3 DT is not much, but this build is stuck with an armor that can make full use of this feat
The number of feats listed above already number 23, while each character only gets a maximum of 17 feats (16 if you leave 1 feat for increased +2 stat)
Ability requirements:
- 11 strength for Iron Grip
- As much Dex as possible
- For Throwing skill for Spear Throw
- For crit chance for sword
- For Melee skill
- 6 Agi for Sprint, 7 Agi for Hit and Run, as much Agi as possible for movement points
- Con - melee build, stuck with an armor that does not offer impenetrable defences, any extra Con is welcome
- 6 Int for Weaponsmith
This build needs ability points all over the place, very hard to build.
These different abilities are all fighting for specialization points:
- Spear Throw - full 15 points to turn it into a low AP nuke
- Shield Bash - full 15 points to turn it into a 0-AP, free nuke every turn
- Critical Power + Cheap Shots: full 15 points into these 2 specializations turn critical hits into instant kills
- Not to mention other feats which could use spec points for further improvement
So all in all, no
