Taji's weapon

Name: Retractable Spear
Type:Retractable Spear X2 /Artifact
Description:

Spoiler:

These spears are roughly 3.5 ft in total length when fully retracted and can be extended to a maximum of 6 feet when fully extended. They sport a gunmetal color and are highly conductive, capable of attracting electricity in all forms too it. Inside of each of the spears (they're are two of them and they're identical) there are 5 lacrima, these lacrima are called Converter Lacrima specially made and bought of the black market. They take heat, kinetic energy and electricity/magical electricity and convert it into real electricity and stores inside of the lacrima themselves. All spells under S rank are capable of charging this weapon, if hit by heat or lightning the weapon will gain 1 full charge (per source) and as for kinetic energy, for each post it is in movement it will gain 1 full charge.
Strengths:
- Extremely sharp
- Conducts/attracts electricity
- Increases the user's magical power by 100% (passive for all artifact weapons)
Weaknesses:
- Spell's bound to the weapon are dependant upon the lacrima inside of it
- A single S rank spell can break this weapon

Abilities:

Name: Lightning Chain
Rank: D
Type: Lightning
Description: The user is able to call forth a chain of lightning which will attach from the bottom of the spear to the users hand, the chain its self will cause D rank electric damage if touched and it will also electrify the spear its self to the same effect. This magic runs off of the charged lacrima within the spears, for each post this is maintained it will drain half of a lacrima.
Strengths:
- Electrifies the weapon
- Allows the weapon to be used at long ranges
- Causes shock burn if touched.
Weaknesses:

Name: Electric wrecking ball
Rank: D
Type: Lightning
Description: The charges within the Lacrima located inside of the spears can exert a field of electricity around the spears the size of a wrecking ball, these fields are physically manifested and are capable of causing physical damage equal to the power of an Artifact weapon as well as D rank electrical damage.
Strengths:
- Can be pretty destructive as it basically enables the user to create a wrecking ball
- Causes D rank electrical damage
Weaknesses:
- Dependent upon the spears having charges.
- For each post this stays active it will use up one full charge.

I need to see all possible strengths and weaknesses for the abilities and the description thank you.
