不能，请注意效果线之类的效果1. 次元锚是射线，射中后才会有效果，飞起来对着坑里射，应该是不会影响效果线的吧。（就好像我仍然可以对着坑里灼热射线）
而且
对于施法时已经处在灵体和星界形态的生物，次元锚对其移动没有影响，次元锚也不会影响跨维度感知和攻击形式
我的理解是，次元坑只是将原来的表面用魔法向下拉伸，形成的坑。受害者并没有进入其他次元，依然处于原先的表面所在的空间（或者说，坑表面依然是正常的，另一侧才是异次元）。你是说，就像把一个塑料袋塞进次元袋吗（
所以次元锚大多数情况下对受害者没有什么影响。
Create Pit
School conjuration (creation); Level sorcerer/wizard 2, summoner/unchained summoner 2; Subdomain caves 2; Elemental School earth 2
CASTING
Casting Time 1 standard action
Components V, S, F (miniature shovel costing 10 gp)
EFFECT
Range medium (100 ft. + 10 ft./level)
Effect 10-ft.-by-10-ft. hole, 10 ft. deep/2 levels
Duration 1 round + 1 round/level
Saving Throw Reflex negates; Spell Resistance no
DESCRIPTION
You create a 10-foot-by-10-foot extra-dimensional hole with a depth of 10 feet per two caster levels (maximum 30 feet). You must create the pit on a horizontal surface of sufficient size. Since it extends into another dimension, the pit has no weight and does not otherwise displace the original underlying material. You can create the pit in the deck of a ship as easily as in a dungeon floor or the ground of a forest. Any creature standing in the area where you first conjured the pit must make a Reflex saving throw to jump to safety in the nearest open space. In addition, the edges of the pit are sloped, and any creature ending its turn on a square adjacent to the pit must make a Reflex saving throw with a +2 bonus to avoid falling into it. Creatures subjected to an effect intended to push them into the pit (such as bull rush) do not get a saving throw to avoid falling in if they are affected by the pushing effect.
Creatures who fall into the pit take falling damage as normal. The pit’s coarse stone walls have a Climb DC of 25. When the duration of the spell ends, creatures within the hole rise up with the bottom of the pit until they are standing on the surface over the course of a single round.
Dimensional Anchor
School abjuration; Level cleric/oracle 4, inquisitor 3, sorcerer/wizard 4, summoner 3, unchained summoner 4; Subdomain wards 4
CASTING
Casting Time 1 standard action
Components V, S
EFFECT
Range medium (100 ft. + 10 ft./level)
Effect ray
Duration 1 min./level
Saving Throw none; Spell Resistance yes (object)
DESCRIPTION
A green ray springs from your hand. You must make a ranged touch attack to hit the target. Any creature or object struck by the ray is covered with a shimmering emerald field that completely blocks extradimensional travel. Forms of movement barred by a dimensional anchor include astral projection, blink, dimension door, ethereal jaunt, etherealness, gate, maze, plane shift, shadow walk, teleport, and similar spell-like abilities. The spell also prevents the use of a gate or teleportation circle for the duration of the spell.
A dimensional anchor does not interfere with the movement of creatures already in ethereal or astral form when the spell is cast, nor does it block extradimensional perception or attack forms. Also, dimensional anchor does not prevent summoned creatures from disappearing at the end of a summoning spell.
完全阻止跨維度旅行 (extradimensional travel)只是一個描述，後面次元錨舉例的，就是「跨維度旅行」的方式呢? (如果真是這樣，我想我用攀爬技能，應該完全沒有牽涉到法術所阻擋的各種跨維度旅行的方法)
突然想起這個帖子。
那照這樣說，其實拋次元錨的意義不大啊。我可以爬牆爬出來(不要太非洲的骰子+猴爪魚鰭藥水/其他幫助攀爬的東西)；使用飛行術飛出來...等等非跨維度旅行的手段。
