The paragraph under "Equipment progression Pathways" in Optimization Academy of Lore: Builds, Expectations explains how to use my guide:
Arrows trailing a linked item indicate a purchase pathway progression through leveling. Certain items are linked at specific tiers with unique names as that is when the player should replace their current equipment with a new series. Arrows only correctly point to the item when the browser window is not restricted to a small area causing the furthest right words to appear on the next line under.
Items of Defensive and Offensive natures identifiy more closely with the nature on the left and less on the right, those on the lesser end are mixtures of both natures, the nature that constitutes the item the most by melee power determines the category it goes into. Items separated by commas and bounded by arrows (A, R > T, X) are on the same power tier, tiers are determined by the accuracy of the penalty for an equivalent status with respect to rounding and balance errors.
Items separated by ">" means at least one of the three undertlined and bolded sentences, there isn't really too much of the underlined sentence going on for leveling up except for spells, since older spells have more Stat% than modern spells, and thus have a series ">" trailing each spell.
Sedna's Chaos pedia page rounds its Control MC effect to 3.88%, the exact value is 5*.4/(129*.4) = 3.87596%, therefore its slightly stronger than a standard MC and as Control is a mixture of 10% melee Offensive and 119% melee Defensive it belongs on the right end,
Emodjinn is a standard pet its not MC thus its on a lower tier as indicated by being on the left side of the ">" to Sedna's Chaos.
Cephalopod despite being MC is improperly balanced as its -26.4 BtH Blind *.85*5*1.4*.5/4.25 = 18.48% melee, instead of 22% melee as explained in GBI for Sand Scurrier, Nerfpets, Cephalopod, thus 18.48+20% melee =38.48% melee which is weaker than a standard pet's 40% melee and should remain on the leftmost power tier indicated by ">".
Click Captain Rhubarb's hand for the treasure hunt map quest for Cephalopod, and pick the Challenge fight in the end to unlock the proper shop for the pet.
