Templar

Believing that the power of magic has become too powerful, the order of the templar has committed itself to training themselves in a fighting style in the specific purpose of combating the power of magic users. In both sword and shield technique, they have trained to be as effective as they can against spells and the mages that cast them.

Antimagic Martial Training

When you take this archetype at 3rd level, you begin to master your antimagic training. While wielding a shield, you get a +3 to your AC against spell attack rolls and a +2 to dexterity saves against spells. However, this focus of deflecting spells reduces your ability to block physical attacks, so the shield only provides a +1 bonus to physical attacks.

Templar Sight

Starting at 3rd level, you begin to master your trained powers to defeat mages. You can use See Invisibility once a long rest without needing material components. You gain additional uses of this feature at 10th level and again at 15th level.

Templar Magic

Sometimes you need to use your opponent's abilities to balance their power. Starting at 7th level, you gain further mastery over your magical training. You can cast Counterspell and Dispel Magic at third level. You can use this ability 3 times per long rest. Intelligence is your spellcasting ability for these spells. At 15th level, you gain an additional 2 uses of this feature, and can expend 3 uses of the feature to cast the spell at 6th level. At 18th level, you gain another 2 uses of this feature, and can expend all uses to cast at ninth level.

Attention to Detail

At 10th level, you begin to understand the casting process of mages in the battlefield and have recognised a weakness in stance right after a spell is cast. While holding a melee weapon, if a creature within 5 feet beyond your reach casts a spell, you can use your reaction to lunge forward and make a single attack against this creature. If you are wielding a ranged weapon, if a creature casts a spell within the lower range of your weapon, you can use your reaction to make a ranged attack against this creature. If a creature takes damage from this attack and are concentrating on a spell, the DC to maintain concentration on the spell increases by 4.

Refined Martial Training

At 15th level, you refine your use of a shield against magic. You now gain a +5 bonus to AC against spell attacks and a +4 to dexterity saves against spells. As an action, you can impose disadvantage on the next spell attack to target you. You can also use your reaction to gain advantage on a dexterity save against a spell.

Templar Master

At 18th level, you gain the capstone ability of Templar training. Once a day, you can cast Antimagic Field without material components. The spell is amplified and extends to a radius of 25 feet. However, maintaining this field takes the utmost focus. In battle while maintaining this field, you cannot take any actions, bonus actions, or reactions. If you do not move on your turn while focusing, you enter a defensive stance and gain an additional +6 to AC and do not need to make concentration checks upon taking damage.
