Enlarge Person Spell (Optibuilds’ Notes) Rating 10/10 alchemist 1, magus 1,sorcerer/wizard 1, summoner 1, witch 1
Enlarge Person is a great first level arcane spell.to be prepare, learn or cast through wand or scroll. Cast it on a front line PC and he gains reach, takes up twice the space, and does more damage with each attack. The typical medium character goes from guarding a 15 x 15 square to guarding 30 x 30 square. This is like a low level wall spell for a caster.
Cast this spell on a front liner with combat reflexes to get the most protection you can. If you are a front liner, drink the potion. Buy a wand and cast it on yourself, assuming you can. Have someone else cast it on you with your wand.
I have a Cleric that uses EP with Lead Blades to increase his weapon damage by 2 steps. I often use this trick while wielding a Holy Ice Weapon – a 2nd level spell that creates a frozen holy water weapon – cast with a Rime Metamagic Rod to inflict the entangled condition for 2 rounds with each hit. This trick also works with the Instant Weapon spell (made of force!) and a Toppling metamagic rod which grants a trip attempt each time you hit. Both are extremely worth it to cast with the Empower meta magic feat for an extra 50% damage.
