Grenadier

You specialize in throwing highly explosive portable ordnances. You become trained with grenades. You gain the Quick Toss action.

You can throw grenades a ridiculously long distance while maintaining accuracy. When you throw a grenade, it has a range of 140 feet, instead of the usual 70 feet.

You count grenades as an area weapon with the area (burst) trait for the purposes of all soldier feats and class features, including primary target and suppressing fire. If you're holding a grenade, you meet the requirements for soldier feats that require you to wield an area weapon.

When you use primary target with a grenade, the grenade counts as a simple thrown weapon with expend 0, the area (burst) trait, and a range of 70 feet (or 140 feet if you have the Long Thrower feat). The Strike against the grenade's primary target deals one damage die of the same dice size and damage type dealt by the grenade. This damage increases to two damage dice if the grenade is advanced or superior, to three damage dice if the grenade is elite or ultimate, or to four damage dice if the grenade is paragon. If the grenade doesn't usually deal damage, it doesn't deal damage using primary target.

You can put just the right spin on your grenade tosses to avoid hitting your friends or yourself. Whenever you Area Fire a grenade, you can select up to four creatures within the grenade’s area; these creatures are unaffected by the grenade until the end of the Area Fire action.

You know how to take advantage of your enemies getting distracted by your explosions. A creature that fails or critically fails a saving throw against a grenade you throw additionally becomes off-guard against the next attack you make against it before the end of your turn.

You can bounce grenades off solid surfaces up to three times before they explode, rather than once. You don’t need to see the surfaces, but you do need to have a general idea of where they are. If the grenade hits a solid surface you didn’t expect to be there, it explodes. For example, if you toss a grenade down a hall you can’t see completely, the grenade will bounce off the hall’s walls and doors but would explode if it hit a chair or a janitor’s cart.

You know how to throw your grenades to deal severe structural damage. All grenades you throw gain the razing trait.

You Quick Toss twice. Any creature in the area of the first grenade gains a +2 circumstance bonus to its saving throw against the second grenade.
