Em relação ao Googles da Horizon, de acordo com o Complete Mage p.133, ele afeta armas de projéteis e armas lançadas somente :
Horizon Goggles These lenses greatly increase your prowess with ranged attacks, allowing you to accurately strike targets much farther away than normal. Description: These goggles feature small oval lenses in a wire-thin frame. When worn, they are difficult (Spot DC 15) for others to notice. The world seems particularly clear and three-dimensional when viewed through the goggles, which glow faintly any time you nock a bow or otherwise prepare to use a ranged weapon. Activation: Horizon goggles are active as long as they are worn; they require no special action to activate. Effect: Horizon goggles grant you the benefits of the Far Shot feat (increases range increment of projectile weapons by 50%, and of thrown weapons by 100%).
De acordo com a definição de Dissolving Spittle, é um ataque por toque à distância, ou seja, uma coisa completamente distinta:
DISSOLVING SPITTLE Descriptors: Acid Classes: Incarnate Chakra: Throat Saving Throw: None Incarnum forms a metallic blue-green torc around your neck. The ends of the torc resemble black or copper dragons facing each other in front of your throat. A constant bitter taste fl oods your mouth, but it seems to make the fl avor of certain foods more enjoyable—particularly well-cooked meat. The infamous incarnate Murthien the Soul-Render, for all his forays into the abomination that is necrocarnum, also used dissolving spittle almost as a calling card. While this meld is favored by chaotic and evil incarnates because of acid’s association with both suffering and dissolution, incarnates of all alignments fi nd acidic spittle a useful weapon against a variety of opponents. As a standard action, you can spit a glob of acid at a target within 30 feet. This requires a ranged touch attack to hit and deals 1d6 points of acid damage. Using dissolving spittle provokes attacks of opportunity. Essentia: Every point of essentia you invest in your dissolving spittle increases the damage dealt by 1d6 points.
Então não faça isso.
Sobre a Rod, diz, quando se refere a ampliar:
ENLARGE SPELL [METAMAGIC] Benefit: You can alter a spell with a range of close, medium, or long to increase its range by 100%. An enlarged spell with a range of close now has a range of 50 ft. + 5 ft./level, while medium-range spells have a range of 200 ft. + 20 ft./level and long-range spells have a range of 800 ft. + 80 ft./level. An enlarged spell uses up a spell slot one level higher than the spell’s actual level.
Magias cujos intervalos não são definidos pela distância, assim como magias cujos intervalos não são próximos, médios ou longos, não têm intervalos maiores.
Desde as fusões de alma:
Soulmelds interact with spells and spells interact with soulmelds in the same way that a spell or a normal spell-like ability interacts with another spell or spell-like ability," and, "Spells, spell-like abilities, and magic items that could potentially affect soulmelds do affect soulmelds.
Eu acho que funcionaria, RAW.
Eu não permitiria que ele tivesse um item que fosse menos caro do que a barra de aumento, fora de equilíbrio: você precisa comparar itens de igual poder e seu preço deveria ser comparável. Se não, por que esse item seria criado ou comprado? Eles se tornam inúteis.
Se isso não o torna mais strong do que uma classe comparável, deve ser aceitável. A maioria das classes de conjuração pode ter muitos bons feitiços a longa distância ...
