Battlespell Shaping

The iconic image of an arcanist is a mage surrounded by enemies, unleashing arcane forces against wide swathes of the opposition at once. Battlespell Shaping allows your battlespells to affect an entire area of the battlefield, rather than a single target.

Base Mastery 1:

You may charge a battlespell with additional power, allowing it to affect an entire area rather than a single target. Choose a single spellshape from the following list.

• Spread - Your battlespell radiates in all direction, affecting every square adjacent to you. This is a melee spellshape.
• Wave - Your battlespell surges forward, affecting an adjacent semi-circle two squares (10') out from you. This is a melee spellshape.
• Cone - Your battlespell blasts forth in a narrow cone. It affect a quarter-circle four squares (20') out from you. This is a melee spellshape.
• Line - Your battlespell carves a single, powerful blast. It affects a line straight out from you and 8 squares (40') long. This is a melee spellshape.
• Burst - Your battlespell explodes some distance from you. Its detonation affects the targeted square and all adjacent squares, covering a 3x3x3 square area. This is a ranged spellshape.
• Split - Your battlespell divides itself into multiple rays. You may target two opponents with your battlespell at a time, making separate attack rolls for each. There are no restrictions on who you may target, except that they must be different people. This is a melee or ranged spellshape.
• Chain - Your battlespell leaps from target to target, doing damage to each. If you hit your original target, you may choose an additional target within 6 squares (30') who must save against the same DC or be affected by the battlespell as well. These additional targets only take half damage from the battlespell, however. You may affect up to 4 additional targets (each within 6 squares (30') of the previous one) as long as each fails their save. This is a melee or ranged spellshape.

You may use the chosen spellshape with any battlespell of a matching type (your battlespell must be capable of being used at range to be used as Burst, for example). You must laden the spell to use a spellshape.

When you use a shaped battlespell, make a single attack roll. Each opponent in the affected area saves against it separately. Otherwise, shaped battlespells are treated identically to a normal battlespell.

Special: Note that the benefits for expanded master levels 3, 5, 7, and 9 are all identical. They are listed as separate mastery abilities because you can't take the same ability more than once.

Expanded Mastery 2:

You gain the ability to form your battlespell into a powerful wall. Casting a wall counts as a ranged attack, and uses the same rules as the spellshapes from the Base Mastery. However, a wall persists on the battlefield until the beginning of your next turn, allowing you to manipulate the terrain at your leisure. A wall covers an area of 6 squares x 1 square (30'x5'), and is 30' high. Walls may only be summoned vertically.

Walls come in three basic forms. When you select this feat choose a single form of wall appropriate to your battlespell from the list below.

• Solid - You cause a flat, vertical wall to spring into being. The wall inserts itself into any surrounding nonliving material if its area is sufficient to do so. The wall cannot be conjured so that it occupies the same space as a creature or another object. It must always be a flat plane, though you can shape its edges to fit the available space. Each 5' section of a solid wall has 30 HP and Hardness 10.
• Energetic - You conjure an immobile curtain of blazing energy into existence. Any creature that passes through the wall or is within the area of the wall when summoned is affected as normal by the shaped battlespell. As well, one side of the wall, chosen by you upon casting, radiates energy out 2 squares (10'), affecting creatures for half damage. You must still make an attack roll to affect creatures with an energetic wall.
• Mixed - You conjure a wall of fragile material, maintained by brimming energy visible inside it. The wall is identical to a solid wall, except that each 5' section of wall has only 5 HP and 0 Hardness. If a creature breaks through the wall, a shimmering field of energy remains, affecting creatures who pass through it as if they were targeted by the battlespell.

Expanded Mastery 3:

You gain greater facility in shaping your battlespells. Choose an additional spellshape from the list given in the Base Mastery.

Expanded Mastery 4:

Rather than blasting your enemies with your power directly, you can release the energies more carefully, filling an area with swirling power for an extended period of time.

Select an area that you can legally target with a battlespell and spellshape that you know. This area fills with arcane energy that harms any who linger too long in it. If a character begins or ends their turn within the area, they are targeted by the battlespell (use standard continuous spell DCs). The swirling energy persists for a number of rounds equal to your Source bonus (minimum 1). This use ladens the spell as usual for a spellshape.

At the time of casting you may choose to assume conscious control of the spell, making it Short duration rather than Constant. As long as you maintain concentration on the spell, the affected area is treated as threatened by you. You may only use the chosen battlespell to take attacks of opportunity provoked within this area. Taking attacks of opportunity use your AoO attempts as normal (see EM8, though).

Expanded Mastery 5:

You gain greater facility in shaping your battlespells. Choose an additional spellshape from the list given in the Base Mastery.

Expanded Mastery 6:

You gain greater control over the form of your walls, allowing you to create walls in any of the three forms at will.

Expanded Mastery 7:

You gain greater facility in shaping your battlespells. Choose an additional spellshape from the list given in the Base Mastery.

Expanded Mastery 8:

When using EM4 to make a persistent spell, you may take an additional number of attacks of opportunity equal to 1+Source bonus. This does not affect how many attacks of opportunity you may make normally.

Expanded Mastery 9:

You gain greater facility in shaping your battlespells. Choose an additional spellshape from the list given in the Base Mastery.

Expanded Mastery 10:

Your control over your shaped spells is absolute. When casting a shaped spell, you may choose to exclude any number of squares from being affected. This allows you to freely cast shaped spells without harming your allies. You may also use this ability when creating a persistent spell with EM4.
