The caster crushes the essence and directs it to the target. The target swells in size but not immediately, the target dose not receive the benefits until the start of of the casters next turn. All magical equipment on the target is affected but non-magical equipment is not. 

The spell does not require concentration if cast as a ritual spell.

The willing target gains the following benefits:

• Increase Size by one step. 
• Double weapon damage, not bonuses or features.
• +4 to total Strength and Constitution. ( IE a +2 to their bonus)
• Advantage on Str/Con saves.
• +10 movement speed.
• Gain temporary hit points equal to one quarter of the targets max hp.

For every 2 levels up cast (7th and 9th) add one size, triple / quadruple, +2 total str/con, +20/30, and equal to third / half.
