[Son of Arathorn]

What's the mini used?

D&D War Drums Warforged Bodyguard.

Sentinel is a solid design. A few issues to consider.

The design lacks a cohesive vision. Is he a commander? Just a rank-and-file soldier? A bodyguard? The combination of Soldier, Loyal, and Combat Leader tend to pull it in different directions. This isn't a major issue, but a change to the class and/or personality could go a long way to bringing the theme together.

Closer to commander than soldier, I'd say. Suppose I changed Soldier to Leader and to Loyal to Disciplined?

"Sentinel" is a cool name, but not one that can be used. The problem is that there is already a class called Sentinel, and even a power that plays off that class, Knight and Sentinel Enhancement. It is not clear if that power is supposed to apply to this figure named Sentinel or not. I'm afraid the name will have to change.

Couple that issue with a design shift towards leader, and I'd say you're right. Could focus on his SA, or on his leadership capabilities (small though they may be). If focusing on the SA, perhaps Hammer/Hammerfell? If focusing on his leadership, Chief, Forefront, Spearhead, Vanguard?

Well SoA... it looks okay. Not sure there's anything wrong with it. It doesn't leap out at me in any great way, though. I do like Combat Leader as a subtle boost for the Warforged, but he doesn't seem to bring them anything new to the table. Heirloom already provides an Area Effect SA, and his is more powerful. I don't understand what Sentinel does that Siege/Heirloom don't already do--aside from the subtle initiative boost, of course.

Since I'd prefer moving towards leader rather than soldier, perhaps enhance his leadership in the most obvious way to differ him from the other Warforged heroes; give him Warforged Leadership. Considering that possibility brings up an interesting point of whether to replace Combat Leader with it, or to eliminate his SA in favor of Leadership.

Suppose the following changes to the design:

Spoiler Alert!

NAME = VANGUARD
GENERAL = VYDAR
PLANET = EBERRON
SPECIES = WARFORGED
UNIQUENESS = UNIQUE HERO
CLASS = LEADER
PERSONALITY = DISCIPLINED
SIZE/HEIGHT = MEDIUM/5

LIFE = 5
MOVE = 5
RANGE = 1
ATTACK = 4
DEFENSE = 2
POINTS = 110/???

COMBAT LEADER
If at least one order marker is on Vanguard, you may add 3 to your initiative roll.

WARFORGED LEADERSHIP
All Warforged you control, except Vanguard, move one additional space.

WARFORGED RESOLVE
When Vanguard rolls defense dice against a normal or special attack, add 1 automatic shield to whatever is rolled.

Conversely, I could move him closer to Soldier than Leader with these changes:

Spoiler Alert!

NAME = CHARGER/???
GENERAL = VYDAR
PLANET = EBERRON
SPECIES = WARFORGED
UNIQUENESS = UNIQUE HERO
CLASS = SOLDIER
PERSONALITY = LOYAL
SIZE/HEIGHT = MEDIUM/5

LIFE = 5
MOVE = 5
RANGE = 1
ATTACK = 4
DEFENSE = 2
POINTS = 110/???

SHIELD BASH
If Charger begins his turn unengaged, opponent's figures roll 1 fewer defense dice when attacked by Charger this turn.

WAR-HAMMER SPECIAL ATTACK
Range 1. Attack 3.
Choose a figure to attack. Any figures adjacent to both Charger and the chosen figure are affected by War-Hammer Special Attack. Roll attack dice once for all affected figures. Each figure rolls defense dice separately.

WARFORGED RESOLVE
When Charger rolls defense dice against a normal or special attack, add 1 automatic shield to whatever is rolled.

I'm more partial to the first, but that's just me.
