Beastmaster could make use of some fixes in his tooltips, and some addition of more information.


1. Wild Axes do not mention their damage/cut radius.
2. Boar's Poison lists a damage type. It does not deal any damage, so it shouldn't show a damage type.
3. Boar's Poison description is too vague. It does not say that the boar's attacks apply the effect.
4. Primal Roar's SHOUT WIDTH: trait shows amplified value when nolding ALT. It's listing an effect width, not a damage amount, it should not show amp'd values.


These are all actual issues.

Here are some extra stuff which could be changed

1. Wild Axes has an unnecessary note telling it pierces spell immunity. Info is already in the header.
2. Wild Axes has an unnecessary note saying it cuts trees. This info is already in the ability description.
3. Call of the Wild: Hawk and Call of the Wild: Boar share the same lore text. A small tweak to both could be applied to have them unique.
3.1 Suggestion for Call of the Wild: Hawk: "After befriending the strange beast of his childhood, Beastmaster has learned to call a scouting hawk to spot even the most hidden foes."
3.2 Suggestion for Call of the Wild: Boar: "After befriending the strange beast of his childhood, Beastmaster has learned to call a fierceful boar to pin down even the fastest foes."
4. Hawk's Invisibility does not have a lore text.
4.1. Suggestion for Invisibility lore: "Using the skies to its advantage, the hawk leaves enemy sight by flying far up into the clouds."
5. Boar's Poison does not have a lore text.
5.1. Suggestion for Poison lore: "The boar's diet of local plants and roots have enriched its spit with various crippling essences."
6. Primal Roar has an unnecessary note telling it pierces spell immunity. Info is already in the header.


Here are some new ALT notes for his spells:

Wild Axes note: The axes fly for a maximum of 2 seconds.
Wild Axes note: The axes spread 353 range apart from each other, trees and enemies inbetween them may not be hit.
Wild Axes note: The axes have 350 range flying vision.
Call of the Wild: Hawk note: Recasting Call of the Wild: Hawk does not replace alredy existing hawks.
Call of the Wild: Hawk note: The hawk is a flying unit, so it has unobstructed pathing and vision.
Call of the Wild: Hawk note: The hawk has a bounty of 30/40/50/60 gold and 77 experience.
Call of the Wild: Boar note: Recasting Call of the Wild: Boar does not replace alredy existing boars.
Call of the Wild: Boar note: The boar has 550 attack range, 1.25 base attack time, 350 movement speed and 1400/800 vision.
Call of the Wild: Boar note: The boar has a bounty of 26-38 gold and 60/70/80/90 experience.
Boar Poison note: Multiple instances of Poison do not stack.
Inner Beast note: Affects invulnerable units.
Primal Roar note: Only enemies are shoved aside, over 300 range for 0.6 seconds.
Primal Roar note: Enemies are fully disabled while getting shoved aside.
Primal Roar note: The pushback and slow have a dynamic range, based on the distance between Beastmaster and the primary target.

Image comparing the changes to the current tooltips (I also changed up the buff and debuff texts a bit, to give them more life)

		"npc_dota_hero_beastmaster_bio"													"Karroch was born a child of the stocks. His mother died in childbirth; his father, a farrier for the Last King of Slom, was trampled to death when he was five. Afterward Karroch was indentured to the king's menagerie, where he grew up among all the beasts of the royal court: lions, apes, fell-deer, and things less known, things barely believed in. When the lad was seven, an explorer brought in a beast like none before seen. Dragged before the King in chains, the beast spoke, though its mouth moved not. Its words: a plea for freedom. The King only laughed and ordered the beast perform for his amusement; and when it refused, struck it with the Mad Scepter and ordered it dragged to the stocks. 
Over the coming months, the boy Karroch sneaked food and medicinal draughts to the wounded creature, but only managed to slow its deterioration. Wordlessly, the beast spoke to the boy, and over time their bond strengthened until the boy found he could hold up his end of a conversation.  He could, in fact, speak now to all the creatures of the King's menagerie. On the night the beast died, a rage came over the boy.  He incited the animals of the court to rebel and threw open their cages to set them amok on the palace grounds.  The Last King was mauled in the mayhem. In the chaos, one regal stag bowed to the boy who had freed him; and with Beastmaster astride him, leapt the high walls of the estate, and escaped. Now a man, Karroch the Beastmaster has not lost his ability to converse with wild creatures. He has grown into a warrior at one with nature's savagery."
In the abilities file, I only removed the damage type line from boar poison and added "CalculateSpellDamageTooltip" "0" to Primal Roar's 4th special value, the damage radius.
