Many knights believe the tower shield is a tool suitable only for troops on the battlefield, claiming it is too large and bulky to use in skirmishes or within dungeon corridors. Sentinels defy those notions, using their massive shields with startling skill and incredible effect. They use these seemingly clumsy shields to perform deft maneuvers that confound their enemies.
The sentinel is an archetype of the knight class.
Burst Barrier (Ex)
At 2nd level, a sentinel can use his shield to screen himself from burst spells and effects, gaining a +1 bonus on Reflex saves against them while employing a tower shield. This bonus increases by +1 for every four levels after 2nd (to a maximum of +5 at 18th level).
This ability replaces stand firm.
Tower Shield Training (Ex)
At 3rd level, a sentinel gains armor training as normal, but while he employs a tower shield, the armor penalty is reduced by 3 and the maximum Dexterity bonus allowed by his armor increases by 2. The benefit increases every four levels thereafter as per standard armor training; if the sentinel is not employing a tower shield, the benefits to armor training revert to the normal bonuses.
Tower Shield Specialist (Ex)
At 5th level, when a sentinel employs a tower shield in combat, he does not take the –2 penalty on attack rolls because of the shield’s encumbrance.
This ability replaces deft shield.
Tower Shield Defense (Ex)
At 6th level, while using a tower shield, a sentinel gains Shield Ward as a bonus feat.
This ability replaces fortress of defense.
Tower Shield Evasion (Ex)
At 13th level, while using a tower shield, the sentinel gains evasion, as the thief class ability. At 19th level, the sentinel gains improved evasion, as the thief advanced talent, while using a tower shield. In addition, his shield cannot be disarmed or sundered.
This ability replaces counterattack and shield ward.
