I've already posted about this idea on beamdog's forums, but this is a more developed version of the idea that I feel I can do because I have learned a bit more about what can be done with near infinity. Also I was considering installing spell revisions and thus my idea was to take advantage of some of the new spells that added. Ultimately though I realised personally that I don't like heavily changing these games. But that said there's still potential additions that could be made so here is the gist of the idea. The basis for it is giving the kit thematic druid spells as innate abilities, with one arcane addition. I also play with a customised spell table that is relatively close to the Icewind Dale spell table but does allow rangers and paladins to gain a couple more level VII spells.
BEAST MASTER: This Ranger is a wanderer and is not comfortable in civilized lands. Therefore, <PRO_HESHE> maintains a natural affinity for animals; they are <PRO_HISHER> friends and comrades-in-arms, and the Beast Master has a limited form of telepathic communication with them.
Advantages:– 3rd level: May cast Animal Summoning I twice per day.
– +15% to Move Silently and Hide In Shadows.
– 3rd level: May cast Animal Summoning I twice per day.
– 5th level: May cast Summon Insects twice per day
– 7th level: May cast Animal Summoning II twice per day.
– 9th level: May cast Call Woodland Beings twice per day
– 11th level: May cast Animal Summoning III twice per day.
– 13th level: May cast Insect Plague twice per day
– 15th level: May cast Conjure Animals twice per day
– 17th level: May cast Call Wyvern twice per day
– 19th level: May cast Creeping Doom twice per day
Disadvantages:
– May not use any metal weapons (for example: swords, halberds, war hammers, or morning stars).
– May not wear armor heavier than studded leather.
The Beastmaster gives up a lot but I feel this would make them a really strong summoner character, that could function pretty closely to say a totemic druid but with better attack capability. (Especially given I like to give them access to Grandmastery.) In practice I find it hard to say if it'd be too overpowered without trying it out, which I plan to, but I'd listen to anyone's insight.
