[New Magic Items] Three Magic Spears

Instead of a standard +1 spear (I've decided to never drop simple +1 weapons in my game, more on that later), my first-level party found one of the following weapons during their latest dungeon crawl.

Spear of the River Spirit

A simple weapon of ancient make, it features a three-pronged barbed spearhead and a shaft made of light, springy wood. Its design is identical to that of the spears that have been used by local fishermen for generations and is crafted of similarly simple materials, though it shows no signs of rust or water damage.

Spear +1/+3 vs. sea creatures with the following additional properties.

• Provides its wielder with a +3 to fishing and swimming checks. 
• The wielder will never lose his or her footing when standing on the deck of a boat.
• If the wielder utters a heartfelt prayer or makes a sacrifice to the River Spirit, has a 1% chance of receiving aid from a friendly 4HD water elemental in time of need. 

Spear of the Black Cat

This six-foot spear presents an imposing sight: the spearhead is a two-foot curved blade of silvery metal, affixed to a shaft of soot-black darkwood.   

Spear +1 with the following properties:

• Stroking the spear or honing the blade will result in it making a purring noise, like that of a cat.
• The owner takes half damage from falls greater than 10' and always lands on his feet.
• During a full moon, enemies have twice the chance to roll a critical fumble when attacking the wielder.  

Spear of the Explorer

This quirky-looking spear is made of three wooden sections, each bearing a brass button. A leather loop attached to the lower section allows it to be easily hooked to a belt or backpack. This utilitarian device was crafted by a conclave of brilliant engineers to fill a request from a renowned (and very wealthy) explorer. He wanted to combine the utility of some of his most valuable spelunking equipment into one device, allowing him to carry more valuables out of any given dungeon.  

Spear +1 with the following properties:

• The spearhead is enchanted with a Continual Light effect, providing full visibility for 60' in all directions. This effect can not be turned off, though the spearhead can be retracted.
• Can be extended to 10' long or collapse down to 3' with retracted blade. Can extend or retract to serve as a 3' club or 6' staff (each also +1). 
• The spearhead can be fired up to 50' away. It acts as a grappling hook and is attached to the staff by a lightweight, knotted silk rope.
