Illusionist Class

Stats

Decay: how quickly Fields shrink. All Illusory Field weapons have a base decay speed, which can be increased or reduced by a percentage. Multiple reductions in decay speed are combined additively, preventing diminishing returns, with a default cap of -35%. Decay reduction means longer-lasting Fields.
Dissipation: how quickly Barriers disappear. All Illusory Barrier weapons have a base dissipation speed, which can be increased or reduced by a percentage. Multiple reductions in decay are combined additively, preventing diminishing returns, with a default cap of -35%. Dissipation reduction means longer-lasting
Fade: how quickly Blurs' particles vanish. All Illusory Blur weapons have a base fade speed, which can be increased or reduced by a percentage. Multiple reductions in fade speed are combined additively, preventing diminishing returns, with a default cap of -35%. Dissipation reduction means longer blurs.
Barrier speed: how quickly Barriers can be placed. This does not benefit from tile or wall placement speed. No hard cap.
Magnification: a bonus to how large a field is when it's deployed. Multiple increases to magnification are combined additively with a hard cap at +150%.
Reach: a bonus to how far away from the player barriers can be placed, in tiles. Reach caps at +10.

Illusionists have two main types of weapons: Fields and Barriers. The fields and barriers can be optical illusions, auditory illusions, or tactile illusions. Optical illusions cannot deal critical hits.

Weapons

Fields

Fields appear as areas that persist and follow the player, with the player always at the area's center. Fields "decay" (shrink) over time, meaning that they have to be refreshed, some more frequently than others. Fields deal no damage to projectiles. For reference, HERE is the size of an Inferno Potion. Credits to the Official Terraria Wiki for the image.

Type	Damage	Knockback	Size	Decay Speed
Optical	Low	None	Large	Slow
Auditory	High	Medium	Medium	Fast
Tactile	Medium	Very High	Small	Medium

Optical Fields

Optical fields are large in size (between 1 and 1.5 times the size of an Inferno Potion) and decay slowly, but do not apply knockback and are generally low-damage for their tier. Their main purpose is to apply debuffs to enemies currently directly within them.

Auditory Fields

Auditory fields are medium in size (between .5 and .75 times the size of an Inferno Potion) and do high damage and medium knockback, but decrease in size very quickly. Their main purpose is to be used as an "active" field.

Tactile Fields

Tactile fields are very small (between .25 and .5 times the size of an Inferno Potion) and decay at a medium rate, and do medium damage and very high knockback. Their main purpose is to keep smaller, faster enemies off of your back, or reward you for taking risks and getting in close (similar to Battle Rods's fishing knives).

Barriers

Barriers appear as blocks that are placed, but "dissipate" (break) after a short delay, similar to the blocks placed by the Ice Rod. Unlike the Ice Rod, which damages by launching projectiles, the blocks themselves are what deal damage. Barriers deal damage repeatedly to enemies that are touching them. All barrier types have a limit to how many can be placed at once, similar to a sentry or minion limit. When the limit is reached, placing a barrier will destroy the first one placed. All barrier types deal the same amount of damage for their tier.

Type	Knockback	Interaction	Placement Range	Placement Speed	Placement Limit	Decay Speed
Optical	Low	As if air	15 Tiles	Very Fast	Low	Fast
Auditory	Medium	As if platform	10 Tiles	Very Slow	Very High	Very Slow
Tactile	High	As if block	5 Tiles	Medium	Medium	Medium

Optical Barriers

Optical barriers dissipate very quickly and relatively few blocks can be active at once, but they can be placed virtually anywhere on screen, and can be placed very quickly. They deal no knockback. Optical barriers can damage projectiles, and block projectiles that don't go through blocks, but do not interact with enemy or player movement. Their main function is to build small shields to block projectiles, and attack targets that are immune to knockback and pass through walls (such as most bosses).

Name	Type	Obtaining
Demonite Lens	Barrier - Optical	10 Demonite Bars at an Anvil
Crimtane Lens	Barrier - Optical	10 Crimtane Bars at an Anvil
Wine Lens	Barrier - Optical	Dropped by Bacchus

Auditory Barriers

Auditory barriers can be placed from a medium distance and last for the longest, and you can have a very large number of them active at a time, but are placed somewhat slowly. They deal medium knockback. Auditory barriers do not block or damage projectiles, and act as platforms for purposes of player or enemy movement. Their main function is to control an area, and attack targets that are large and stay in (or repeatedly pass through) a specific area (like most bosses).

	Yellow Yell	Sold by Traveling Artist
	Vulpine Flute	Dropped by Plantera (15% chance)

Tactile Barriers

Tactile barriers can be placed at and dissipate at a medium speed, and a good number of them can be placed at once, but not as many as auditory barriers. They deal high knockback. Tactile barriers damage and block projectiles, and also block player and enemy movement. Their main function is to stop enemies from going into a certain area, box small groups of enemies in (damaging them very quickly since they're constantly in contact with the blocks this way), and to be used as mundane transportation (such as resetting wing flight time).

Name	Obtaining	Other
Paper Claw		Enemies that touch side of barrier are knocked further back and are inflicted Bleeding
Meteor Mitt	20 Meteorite Bars at a Pre-Hardmode Anvil	Enemies standing directly on top of barrier are set On Fire!
Fungal Gauntlet	20 Fungal Chitin at a Pre-Hardmode Anvil	Barrier constantly releases Fungal Spores

Blurs

Blurs, while in use, leave a projectile at the player's current position, resulting in a trail behind the player as the player moves. The faster the player moves, the more damage is dealt by the projectiles made at that time.

Type	Knockback	Width	Fade Speed
Optical	Low	3 tiles	Slow
Auditory	Medium	9 tiles	Medium
Tactile	High	3 tiles	Fast
